= Diplodocia Tornier, 1913
Comments- While Cope (1883) used Opisthocoela as an alternative name for Sauropoda, it is actually a misspelling of Owen's (1860) Opisthocoelia. As Opisthocoelia was erected to include not only "Cetiosaurus" medius and Pelorosaurus but also the theropod Streptospondylus, it is a better equivalent of Saurischia than Sauropoda. Tornier (1913) used Diplodocia as an alternative name for Sauropoda.

Leonerasaurus Pol, Garrido and Cerda, 2011
L. taquetrensis Pol, Garrdo and Cerda, 2011
Early Pliensbachian, Early Jurassic
Upper Member of the Las Leoneras Formation, Chubut, Argentina
Holotype- (MPEF-PV 1663) partial dentary, three teeth, incomplete axis, incomplete third cervical vertebra (40.8 mm), incomplete fourth cervical vertebra (47.1 mm), incomplete fifth cervical vertebra (50.8 mm), partial sixth cervical vertebra, partial seventh cervical vertebra, partial eighth cervical vertebra, ninth cervical vertebra, tenth cervical vertebra, incomplete first dorsal vertebra (40.1 mm), incomplete second dorsal vertebra (38 mm), incomplete third dorsal vertebra (41.8 mm), partial fourth dorsal vertebra (42.3 mm), fifth dorsal vertebra, ?sixth dorsal vertebra, incomplete mid dorsal vertebra (42.7 mm), incomplete mid dorsal vertebra, incomplete mid dorsal vertebra, fragmentary posterior dorsal vertebrae, dorsal ribs, incomplete first sacral vertebra (46.9 mm), incomplete fused second and third sacral vertebra (43, 43 mm), partial fourth sacral vertebra, incomplete scapula, incomplete humerus (202.8 mm), incomplete ilia, pubic fragment, incomplete ischium, femoral fragment, metatarsal I (67 mm), partial metatarsal II, incomplete pedal ungual
Diagnosis- (after Pol et al., 2011) anterior teeth with low, spoon-shaped crowns (SI = 1.3); dorsosacral rib attached to preacetabular process of ilium (also in Lufengosaurus); primordial sacral neural arches positioned on anterior half of centrum; caudosacral rib directed anterolaterally; deltopectoral crest low and medially deflected along distal half; flattened ischial shafts (also in Anchisaurus).
Comments- Pol et al. (2011) added Leonerasaurus to Yates' sauropodomorph matrix and recovered it as sister to Melanorosaurus+Sauropoda. More recently, McPhee et al. (2015) recovered Leonerasaurus as sauropod more derived than Antetonitrus and Lessemsaurus, but more basal than other included sauropods.

Chinshakiangosaurus

"Damalosaurus" Zhao, 1983
= "Damalasaurus" Zhao, 1985
"D. laticostalis" Zhao, 1985
?= "Damalasaurus magnus" Zhao, 1985
Etymology- Named for Damala Mountain in Qamdo, with the species referring to wide ribs (laticostalis) or large size (magnus).
Early Jurassic
Middle Daye Group, Daye, Qamdo County, Tibet, China
Material- (~15 m) specimen including dorsal rib
Comments- The species is listed as "magnus" in the text, but "laticostalis" in the plate caption. Olshevsky (1991) listed "laticostalis as the type, though I consider it probable only one species is intended by Zhao since two are never present in faunal lists together (Zhao and Cheng, 1985; Zhang and Li, 1997; Fang et al., 2006). Fang et al. use "laticostalis" for the species, suggesting it is the intended one since Zhao is a coauthor. Zhao (1985) includes a photograph of a dorsal rib in situ, which the length estimate above is taken from assuming proportions like Barapasaurus. Glut (1997) incorrectly stated it is Middle Jurassic in age. Weishampel et al. (2004) list this as an undescribed sauropod in their faunal list.
Relationships- Stated by Zhao (1983, 1985) to be a primitive sauropod. Chure and McIntosh (1989) listed it as a cetiosaurid, while Lambert (1990) and Olshevsky (1991) listed it as a brachiosaurid. Glut (1997) only listed it as Sauropoda incertae sedis. Fang et al. (2006) place it in Cetiosauridae, noting again it's a primitive sauropod. As those authors placing it in Brachiosauridae have never seen the specimen, and brachiosaurids are currently unknown from Asia or the Early Jurassic, that assignment seems less likely. Since Cetiosauridae is currently viewed as a grade of basal eusauropods, "Damalosaurus" is here placed as Sauropoda incertae sedis.

"Yibinosaurus" Ouyang vide anonymous, 2001
"Y. zhoui" Ouyang vide anonymous, 2001
Toarcian, Early Jurassic
Dongyuemiao Member of Ziliujing Formation, Sichuan, China
Material- (Chongqing Museum of Natural History coll.) specimen including dorsal vertebrae
Comments- This name originally appeared in a guidebook, with the taxon stated to be under study by Ouyang. Ouyang (2003) later mentioned it in his thesis as a new genus, which he places in an eponymous subfamily within Vulcanodontidae. As he also includes the more basal Gongxianosaurus in Vulcanodontidae, Ouyang's conception of the family may be more of a grade. Ouyang further notes the anterior dorsal neural spines are transversely expanded, which he believes indicates a possible relationship to taxa with bifurcated spines like Datousaurus. As Ouyang states "Yibinosaurus" is from the same locality as Gongxianosaurus, the dorsal vertebrae, 51 articulated caudal vertebrae, scapulae and ilium mentioned by Luo and Wang (1999) as Gongxianosaurus sp. nov. may be the "Yibinosaurus" material.

Gongxianosaurus

Kunmingosaurus Zhao vide Dong, 1992
K. wudingensis Zhao vide Dong, 1992
= "Kunmingosaurus wudingi" Zhao, 1985
= "Kunmingosaurus utingensjs" Zhao, 1985
= "Kunmingosaurus utingi" Zhen, Li and Rao, 1986
= "Kunmingosaurus wudingensis" anonymous, 1990 vide Olshevsky, 1991
Etymology- Kunming is the capital city of Yunnan, while Wuding is the county and basin the specimen was found in.
Hettangian, Early Jurassic
Zhangjiawa Member of the Lufeng Formation, Hoshaofang, Wuding County, Yunnan, China
Syntypes- (IVPP coll.) (~11 m) incomplete skeleton including dorsal vertebrae, eight proximal caudal vertebrae, four chevrons, ilium, pubis, femur (~847 mm), tibia, fibula, astragalus, metatarsal I, phalanx I-1, pedal ungual I, metatarsal II, phalanx II-1, pedal ungual II, metatarsal III, phalanx III-1, phalanx III-2, pedal ungual III, metatarsal IV, phalanx IV-1, metatarsal V, phalanx V-1
....(BNHM,PZGR 74) dentary (Young, 1966)
....(BNHM,PZGR 75) dentary (Young, 1966)
Referred- ?(FMNH CUP 2042) maxilla (Barrett, 1999)
?(IVPP coll.) tooth (Upchurch and Barrett, 2000)
Comments- The species name is spelled "wudingi" in the text, and "utingensjs" in the figure caption, which as noted by Chure and McIntosh (1989) are probably unintentional variants, and the latter no doubt a mispelling of "utingensis".
The skeleton was discovered by Su in 1954, but the dentaries were only discovered later in 1960 and described and illustrated by Young (1966) as specimens of Lufengosaurus magnus. Dong (1992) referred them to the same individual as the postcrania since they came from the same quarry. While Dong (and later Olshevsky, 2000) was incorrect in stating Zhao described the taxon in 1985, his own book contains a diagnosis, type and illustration so would seem to validate the nomenclature (contra Barrett, 1999). Indeed, Upchurch et al. (2004) attribute the name to Dong, 1992. A photo of part of the mounted skeleton is in Zhao (1985), contra Barrett (1999). Dong et al. (1990) published a photograph of the entire skeleton, and several are available online as well. Li et al. (2010) note Kunmingosaurus lacks dorsal pleurocoels and has a poorly developed fourth trochanter.
Simmons (1965) described a maxilla (FMNH CUP 2042) from Ta Ti in the same beds as Yunnanosaurus robustus, which is similar to Kunmingosaurus in having a sauropodan lateral plate and serrated, spatulate teeth with a lingual ridge. Barrett (1999) redescribed it as a sauropod maxilla, though he did not refer it to any genus. Upchurch and Barrett (2000) described a referred tooth.
Relationships- Stated by Zhao (1985) to be a primitive sauropod. Chure and McIntosh (1989) and Lambert (1990) listed it as a cetiosaurid, while Olshevsky (1991) listed it provisionally as a barapasaurid and Dong (1992) as a shunosaurine camarasaurid. Upchurch and Barrett (2000) discussed it as a 'vulcanodontid', which was a grade of basal sauropods in their scheme, and described a referred tooth. Upchurch (1995) noted there was no published evidence suggesting it was a vulcanodontid, however. He later (1998) noted that Kunmingosaurus' teeth were more plesiomorphic than Barapasaurus, Shunosaurus, Patagosaurus and other taxa in having only a shallow lingual concavity and being quite labiolingually compressed. Barrett (1999) considered the dentaries to be sauropod based on the dorsoventrally expanded symphysis and lateral plate. Fang et al. (2006) list it as a camarasaurid.
When entered into a modified version of Wilson's (2002) analysis, Kunmingosaurus emerges more derived than Chinshakiangosaurus, Antetonitrus, Lessemsaurus and Blikanasaurus but less than eusauropods (so is not a cetiosaurid, barapasaurid, shunosaurid or camarasaurid). It is thus related to taxa such as Gongxianosaurus, Kotasaurus, Spinophorosaurus, Tazoudasaurus and Vulcanodon, so may be considered vulcanodont-grade. Note the results agree with Upchurch's (1998) statements, though his dental characters were not used by Wilson. Specifically, Kunmingosaurus is more derived than Chinshakiangosaurus based on the D-shaped teeth and reduced fourth trochanter, but less derived than Shunosaurus based on no crown-to-crown occlusion, straight dorsal ilial margin and unreduced pedal phalanges.

Archaeodontosaurus Buffetaut, 2005
A. descouensi Buffetaut, 2005
Bathonian, Middle Jurassic
Isalo IIIb Formation, Madagascar
Holotype- (MHNDPal 2003-396) partial dentary, several teeth
Diagnosis- (after Buffetaut, 2005) dentary which is markedly deeper anteriorly than posteriorly; at least 16 alveoli containing prosauropod-like lanceolate teeth with strong, well-defined denticles, a distinct lingual median ridge, and a finely wrinkled enamel.
Comments- Based on adding the taxon to Yates' sauropodomorph analysis, this is a sauropod less derived than Shunosaurus. A crown which expands markedly mesiodistally compared to the root may indicate it is more derived than Chinshakiangosaurus. However, Flynn et al. (2010) noted the locality and the mosaic of basal and derived features might indicate a relationship to the Malagasy basal archosauromorph Azendohsaurus, but the latter seems to lack a lingual ridge on its teeth and wrinkled enamel.

Eshanosaurus Xu, Zhao and Clark, 2001
E. deguchiianus Xu, Zhao and Clark, 2001
Hettangian, Early Jurassic
Lower Lufeng Formation, Yunnan, China
Holotype- (IVPP V11579) (mandible ~170 mm) dentary, partial splenial
Comments- This taxon was originally identified as a therizinosaur, despite its Early Jurassic age. It may be a sauropodomorph, especially since it lived so much earlier than any other avetheropod, and the fact the much later therizinosaur Falcarius is nonetheless less derived in respect to serration size, dentary curvature and the absence of a lateral dentary ridge. Most recently, Barrett (2009) notes that basal sauropodomorphs lack the anteriorly extensive well defined lateral dentary shelf, anteriorly increasing tooth size, more than thirty dentary teeth, lingual cingulum on teeth, apicobasally oriented lingual ridge on teeth, and tooth roots that expand mesiodistally to equal crown width.

"Rutellum" Lhuyd, 1699
"R. impicatum" Lhuyd, 1699
Jurassic
Coral Rag, England
Material- (University of Oxford coll. #1352; lost) tooth
Comments- Lhuyd (1699) illustrated this as a fish tooth, but the name is invalid as it was published before the earliest date for Linnaean nomenclature. Gunther (1945) referred it to Cetiosaurus. Delair and Sarjeant (2002) called it a cetiosaur. While the broad crown excludes it from Diplodocoidea and Lithostrotia, further resolution is difficult given the single figure. A crown which expands markedly mesiodistally compared to the root may indicate it is more derived than Chinshakiangosaurus.

?(MLP 36-XI-10-3/4) distal tibia (178 mm wide) (Casamiquela, 1963)
Diagnosis- (after Rauhut, 2003) lateral walls of the neural canal and centropostzygapophyseal laminae flared laterally posteriorly; neural canal strongly flexed anteroposteriorly within the dorsal neural arches.
(after Carballido and Pol, 2010) spoon-shaped teeth with low SI values (1.34-1.49); enamel wrinkled forming a pattern of pits and narrow apicobasal sulci; absence of denticles in both mesial and distal margins (also in Kotasaurus and Shunosaurus); wear facets extending mostly along one margin of the crowns.
Other diagnoses- Cabrera (1947) listed several characters in his diagnosis. The teeth were said to be similar to Apatosaurus (as Brontosaurus), but comparatively larger. However, the supposed Apatosaurus tooth cited by Cabrera is from Camarasaurus, so was not correctly associated with the Apatosaurus postcrania. In addition, which postcrania the Amygdalodon teeth belonged to is unknown. Apneumatic dorsal centra with pleurofossae are primitive. A pubis "similar to atlantosaurids" is vague, but may indicate the straight anterior margin noted in the text to be more like Apatosaurus than Cetiosauriscus (as Cetiosaurus leedsi) or Camarasaurus. A straight pubic shaft is also found in taxa such as Tazoudasaurus however.
Comments- Piatnitzky discovered the referred material in 1936 and mentioned it that year, though it was not described until Casamiquela did so in 1963. The type material was collected in 1936 and described the following year by Cabrera as a new taxon of cetiosaurid. Cabrera (1947) identified the dorsal neural spine as a caudal neural spine, while Casamiquela (1963) believed it was a dorsal diapophysis. The flat fragment has been identified as part of a scapula (Cabrera, 1947) and dorsal rib (Casamiquela, 1963), but Rauhut (2003) felt it didn't match any sauropod element and placed it as Reptilia indet.. Camasiquela identified the sacral centrum as a caudal centrum. The material was found in one area, but belongs to at least three individuals, with the cervical prezygapophysis largest, the dorsals medium sized, and the sacral smallest. Which individuals the other material belongs to is unknown, though there are at least two sizes of dorsal ribs. Whether all of the material belongs to the same taxon is unknown, though it is all congruent with a basal sauropod.
Carballido and Pol (2010) recently found this taxon to be a sauropod more derived than Chinshakiangosaurus but outside Gravisauria based on a version of Wilson's analysis. Lang's (2008) unpublished thesis finds it to be a shunosaurid though.

Comments- Unfortunately, the description of "Pulanesaura" has no mention of ZooBank and as of July 5 2020 it lacks an entry on the ZooBank webite. Thus according to ICZN Article 8.5.3 (an electronic work must "be registered in the Official Register of Zoological Nomenclature (ZooBank) (see Article 78.2.4) and contain evidence in the work itself that such registration has occurred"), "Pulanesaura eocollum" McPhee et al., 2015 is a nomen nudum that may never be technically valid as its journal is not published physically.
McPhee et al. (2015) recovered "Pulanesaura" as sister to vulcanodontids+gravisaurians using a version of Yates' matrix.

= "Nebulasaurus taito" Xing, Miyashita, Currie, You, Zhang and Dong, 2013 online
Aalenian-Bajocian, Middle Jurassic
Zhanghe Formation, Yunnan, China
Holotype- (LDRC-v.d.1) incomplete braincase
Diagnosis- (after Xing et al., 2015) exoccipitals nearly excluding supraoccipital from foramen magnum (supraoccipital forms less than a tenth of foramen magnum margin); supraoccipital not expanded laterally between parietal and exoccipital.
Comments- The paper naming this taxon was originally available online in 2013 but did not contain a ZooBank registration, so Nebulasaurus taito was a nomen nudum until officially published in 2015 (ICZN Article 8.5.3). Xing et al. (2015) added it to a version of Harris' sauropod matrix and recovered Nebulasaurus as the sister to Spinophorosaurus, in their phylogeny a non-neosauropod eusauropod.

Zizhongosaurus Dong, Zhou and Zhang, 1983
Z. chuanchengensis Dong, Zhou and Zhang, 1983
Early Jurassic
Daanzhai Member of the Ziliujing Formation, Sichuan, China
Holotype- (IVPP V9067) posterior dorsal neural arch, partial humerus, pubic fragment, fragments
Diagnosis- (after Dong et al., 1983) dorsal vertebrae with high neural spine with an apex as an expanded plate that descends slightly anteriorly and is concave posteriorly; lateral spine surface is ornamented with dorsally radiating vertical striations; diapophyses are well developed to form a right angle with the neural spine at the neural arch; hyposphene present; relatively long forelimbs; humerus with straight and rounded shaft.
Comments- Discovered in the 1980's. Originally referred to Cetiosaurinae and more lately to Vulcanodontidae, Zizhongosaurus has yet to be included in a phylogenetic analysis and will be difficult to evaluate given the brief description and single figure.

Eusauropoda Upchurch, 1995
= Bothrosauropodidae Janensch, 1929
= Bothrosauropodoidea Janensch, 1929 vide Kuhn, 1961
Definition- (Shunosaurus lii + Saltasaurus loricatus) (Wilson, 2005; modified from Upchurch et al., 2004)
Other definitions- (Barapasaurus tagorei + Diplodocus longus) (modified from Salgado et al., 1997)
(Saltasaurus loricatus <- Vulcanodon karibaensis) (Sereno, 2007; modified from Wilson and Sereno, 1998)
Comments- Upchurch (1995) erected Eusauropoda for his clade containing euhelopodids and neosauropods, but not Vulcanodon or Barapasaurus. This makes the explicit inclusion of Barapasaurus in Salgado et al.'s definition problematic. While both Upchurch et al.'s and Wilson and Sereno's definitions have similar current content, only the former equates to Eusauropoda in Upchurch's 1995 topology, so is preferred here.
Janensch (1929) erected Bothrosauropodidae (which is invalid, as there is no genus Bothrosauropus) for cetiosaurines, camarasaurines and brachiosaurines.

Eusauropod indet. (Lapparent and Zbyszewski, 1957)
Late Kimmeridgian, Late Jurassic?
Alcobaca Formation, Portugal
Material- (MMLT 602528; syntype of Megalosaurus pombali) proximal caudal vertebra (130 mm)
Comments- Lapparent and Zbyszewski (1957) referred several vertebrae to their new species of Megalosaurus, M. pombali, including "a very powerful posterior dorsal (Pl. XIII, fig. 31, 32, 33) whose face has a somewhat less triangular shape (Torres Vedras Museum)." However, Mocho et al. (2017) instead referred this to "an anterior
caudal vertebra of an indeterminate sauropod."

Eusauropod indet. (Lapparent and Zbyszewski, 1957)
Tithonian?, Late Jurassic?
Bombarral Formation?, Portugal
Material- (MG 4811; syntype of Megalosaurus pombali) mid-distal caudal vertebra (135 mm)
Comments- Lapparent and Zbyszewski (1957) referred several vertebrae to their new species of Megalosaurus, M. pombali, including "an amphicoelous and elongated posterior caudal (Pl. XIII, fig. 30), very pinched ventrally, was recovered isolated at Albergaria. It shows the powerful tail that this large megalosaur must have had." However, Mocho et al. (2016) instead referred this to Sauropoda indet., as "the presence of an anteroposteriorly short neural arch seems to exclude this caudal vertebra from Theropoda, and its general morphology more closely resembles that of sauropod middle and posterior caudal vertebrae." They could differentiate it from Aragosaurus, Galveosaurus, Lusotitan, diplodocines and titanosauriforms, but not Losillasaurus, Lourinhasaurus, Turiasaurus or Zby. Moch et al. state "In Albergaria dos Doze, the present railway intersect Cretaceous sediments, “Cenomaniano inferior, Albiano, Aptiano, Neocomiano”, nevertheless the referred point is close to the river Arunca, which intersect the Upper Jurassic sediments of the “Complexo Vale de Lagares” (Teixeira et al., 1968) that corresponds to the Alcobaça Formation, Kimmeridgian to basal Tithonian in age." Mocho et al. (2017) later stated it was "probably from the Bombarral Formation."

Rhoetosaurus Longman, 1926
R. brownei Longman, 1926
Bajocian, Middle Jurassic
Hutton Sandstone Formation of the Injune Creek Group, Queensland, Australia
Holotype- (QM F1659) incomplete ?axis (446 mm), cervical vertebra, incomplete anterior dorsal vertebra (220 mm), three posterior dorsal vertebrae (~180 mm), posterior dorsal centrum, partial posterior dorsal centrum, two dorsal rib fragments, incomplete sacrum (16, 21 mm), fragmentary first caudal vertebra, fragmentary second caudal vertebra, fragmentary third caudal vertebra, fragmentary fourth caudal vertebra, incomplete fifth caudal vertebra (140 mm), sixth caudal vertebra (136 mm), incomplete seventh caudal vertebra (137 mm), incomplete eighth caudal vertebra (135 mm), ninth caudal centrum (135 mm), incomplete tenth caudal vertebra (140 mm), eleventh caudal vertebra (142 mm), twelfth caudal centrum (160 mm), thirteenth caudal centrum (150 mm), fourteenth caudal centrum (158 mm), fifteenth caudal centrum (150 mm), sixteenth caudal vertebra (152 mm), seventeenth caudal centrum (158 mm), eighteenth caudal centrum (157 mm), nineteenth caudal centrum (155 mm), twentieth caudal centrum, distal caudal vertebra (157 mm), five distal caudal vertebrae, fragmentary caudal vertebrae, several chevron fragments, ilial fragments, incomplete pubes (~1.2 m), ischial fragments, incomplete femur (~1.53 m), tibia, fibula, astragalus, metatarsal I, phalanx I-1, pedal ungual I, metatarsal II, phalanx II-1, pedal ungual II, metatarsal III, phalanx III-1, phalanx III-2, phalanx III-3, pedal ungual III, metatarsal IV, phalanx IV-1, pedal ungual IV, fragments
Diagnosis- (after Nair and Salisbury, 2009) multiple prominent medial crests on the distal tibia; concentric proximal fossa on the medial surface of the tibia; accessory fossae or grooves on the medial face of pedal unguals.
Comments- The first remains were discovered in 1924, with additional material in 1926 (Longman, 1927). Further material of the type specimen was discovered starting in 1975 and was described with a reanalysis of the taxon by Nair and Salisbury (2012). They find it to be a non-neosauropod gravisaur.

"Lancangosaurus" Zhao, 1980
= "Lancanjiangosaurus" Zhao, 1983
= "Lancangjiangosaurus" Zhao, 1985
= "Lanchangjiangosaurus" Fang, Zhang, Lu, Han, Zhao and Li, 2006
"L. cachuensis" Zhao, 1985
Etymology- The genus references the Lancang Jiang, the local name for the head of the Mekong River. The species name refers to the Zaqu River, which is the upper reaches of the Mekong.
Middle Jurassic
Middle Dapuka Group, Dabuka, Qamdo County, Tibet, China
Material- (~15 m) specimen including skull, mandible, twelve teeth and limb elements
specimen (Fang et al., 2006)
Comments- Though usually believed to be a preliminary name for Datousaurus (e.g. Olshevsky, 1991), "Lancangosaurus" was first reported by Zhao (1980) in relation to a Dapuka specimen, not the Xiashaximiao Datousaurus. Listed characters are large skull, large spatulate teeth which decrease gradually in size posteriorly, a thick mandible and robust limbs. Dong et al. (1983) believed the teeth were congeneric with those from the Wujiaba Quarry of the Shangshaximiao Formation, which they described as belonging to Omeisaurus junghsiensis and O. fuxiensis. Zhao (1985) figures teeth in situ, though the photograph is unclear. Note Olshevsky (1991) switched the authorship for the variants "Lancanjiangosaurus" and "Lancangjiangosaurus". Glut (1997) incorrectly listed it as being Late Jurassic in age. Fang et al. (2006) note additional material from lower in the same formation. Given the etymology, either "Lancangosaurus" or "Lancangjiangosaurus" would be the most accurate names.
Relationships- "Lancanjiangosaurus" was stated by Zhao (1983) to be a bothrosauropodoid, in which he includes spatulate-toothed taxa like camarasaurids and brachiosaurids. Zhao (1985) notes it is a sauropod similar to Cetiosaurus. Chure and McIntosh (1989) listed it as a cetiosaurid, as does Olshevsky (1991) provisionally, while Lambert (1990) listed it as a brachiosaurid. Glut (1997) merely referred it to Sauropoda incertae sedis. Most recently, Fang et al. (2006) place it in Cetiosauridae. The known characters are found in both basal eusauropods like Omeisaurus and camarasaurids, though the age, locality and Zhao's opinion all favor the former identification. Whether Dong et al. are correct in placing it close to Omeisaurus is unknown, and for now I recommend keeping it as Eusauropoda incertae sedis.

Late Callovian-Early Oxfordian, Middle-Late Jurassic
Jiangjunmiao, Lower Shishugou Formation, Xinjiang, China
Holotype- (IVPP V9492) (~17 m, adult) fragmentary teeth (lost), nine mid and posterior cervical vertebrae, twelve dorsal vertebrae, three proximal dorsal ribs (two lost), six sacral vertebrae, four partial proximal caudal vertebrae, ten proximal caudal neural spines (five lost), eleven mid-distal caudal centra (133, 147, ~156, 139, 116, 132, 135, 139, ~76, ~81 mm), four mid to distal chevrons, incomplete scapulocoracoid, humerus (880 mm), ulna (605 mm), radius (~540 mm), two ?carpals (lost), partial ilium, incomplete pubis (lost), partial ischium, femora (one incomplete, one distal; ~1.240 m), tibiae (one partial, one proximal; ~740 mm), fibulae (one partial, one proximal; ~750 mm), partial astragalus, calcaneum (lost), metatarsal I (~130 mm), metatarsal II/III (135 mm), phalanx III-1(?) (63 mm), three pedal phalanges (~66, ~50, ~160 mm), pedal ungual
Diagnosis- (after Moore et al., 2020) scabrous, sheet-like anterior extensions of the SPRLs in middle-posterior cervical vertebrae; oblong, blind pneumatic fossa just anterior to the SDF in middle-posterior cervical vertebrae; triplicate PCPLs in some posterior dorsal vertebrae; dorsally bifurcated SPDL in middle and posterior dorsal vertebrae without confluence with either the SPRL or the SPOL; shelf-like embayment of the proximomedial corner of the anterior face of the humerus, bounded medially by a bulge; flange-like ridge overhanging the medial surface of the shaft of metatarsal I.
Comments- Discovered in 1982 and excavated in 1984. Olshevsky (1991) lists "Klamelisaurus gobiensis" as a euhelopodid (in a sense including mamenchisaurs) "to be described by Zhao C. C. from the Late Jurassic of the Dzungar Basin, Xinjiang; known from a skeleton about 80% complete; SVP Bulletin #149:45." Klamelisaurus was officially described by Zhao (1993) as a brachiosaurid sensu lato closest to camarasaurines but different enough to be in a monotypic subfamily. Moore et al. (2020) redescribed Klamelisaurus in depth, reporting some elements could not be located, others were newly reported, the reported manual elements were pedal, and much of the material was reconstructed making assessment of the original anatomy impossible. Moore et al. recovered it as a euhelopodid (including mamenchisaurs, almost always outside Neosauropoda) closest to, and sometimes nested within, Mamenchisaurus.
Kelmayisaurus "gigantus"- Grady (1993) wrote about visiting the Wucaiwan Formation of Xinjiang in 1987, stating "A few years earlier, Dale [Russell] noted in his field book, a Kelmayisaurus gigantus, a huge theropod measuring twenty-one meters from neck to tailtip (there was no skull) had been found there." Olshevsky (DML, 1995) reported that "Dale says he's never heard of it", suggesting a misunderstanding by Grady. A plausible solution was suggested by Greenfield (online, 2021) that Russell's field book was referring to the sauropod Klamelisaurus gobiensis, whose skull-less holotype was excavated from that formation in 1984. The confusion in names could be due to the fact Klamelisaurus was only officially published in April 1993, although the name "Klamelisaurus gobiensis" had been unofficially proposed since at least June 1990 (Olshevsky, 1991) so could have been in Russell's field book and misinterpreted by Grady as a similar genus and species name. Finally, while Klamelisaurus' holotype was only estimated to be 17 meters by Zhao (1993) once described, the anterior cervicals and distal caudals were not preserved, so Russell's 21 meter report wouldn't be unreasonable especially when done prior to the official description.

Referred- ?(IVPP V8301) seventh cervical vertebra, eighth cervical vertebra, ninth cervical vertebra, tenth cervical vertebra, cervical ribs, seventeen mid caudal vertebrae, chevrons (Dong, 1990)
Late Jurassic
Lamalishan, Xinjiang, China
?(IVPP V932) twentieth caudal vertebra (135 mm) (Young, 1958)
Diagnosis- (after Young, 1937) size moderate; scapula moderately strong, weakly expanded distally; shaft subequal in length with the expanded part plus coracoid; rather short forelimb; ilium with very open anterior embayment; pelvic peduncle set forward; acetabulum perforated but with a broad bony marginal area; ischium massive but not distally expanded; fourth trochanter of femur weak or missing.
(after Dong, 1990) euhelopodid-style cervical vertebrae with long and opisthocoelous centra, ventrally flat and lacking keels; neural spines are low, or pseudospinus; large and long cervical ribs.
Comments- Discovered in 1930. Originally placed as a euhelopodid or camarasaurid, based on a revised version of Wilson's analysis it may be closer to basal taxa like Tazoudasaurus and Spinophorosaurus. It certainly seems to differ from Euhelopus (e.g. in its amphicoelous dorsals) and would have priority over the genus anyway, contra Martin-Rolland (1999).

Diagnosis- (after Bonaparte et al., 2000) anterior dorsal vertebrae opisthocoelous; neural spines low, continuous with diapophysis and anteroposteriorly laminar; neural spines do not rise above neural arch; diapophysis elongated with dorsal depression lateral to prezygapophysis; diapophysis with deep anterior cavities and shallower posterior cavities; well developed infradiapophyseal laminae; epipophyses strong and thick, near dorsalmost border of vertebra and connect with diapophyses.
Comments- Discovered between 1909 and 1912. First referred to Janenschia robusta (as Gigantosaurus robustus) by Janensch (1929), they may actually belong to that species. Bonaparte et al. (2000) assigned it to a new neosauropod family, but preliminary analyses suggest it may be related to near-neosauropod taxa like Jobaria and Cetiosaurus instead. The caudal series is only tentatively referred because it was associated with MB.R.2091.31.

Amoreira-Porto Novo Member of Lourinha Formation, Portugal
Holotype- (ML 368) tooth (38x28x14 mm), mid-posterior cervical neural arch fragment, incomplete proximal chevron, proximal scapula, coracoid (569 mm), humerus (1.53 m), radius (1.04 m), ulna (1.06 m), metacarpal I (365 mm), phalanx I-1 (82 mm), manual ungual I (172 mm), phalanx ?II-1 (47 mm), metacarpal III (398 mm), metacarpal IV (382 mm)
Diagnosis- (after Mateus et al., 2014) posterior margin of scapula just proximal to blade at an abrupt angle (~110 degrees) to proximalmost posterior margin of scapular blade; humerus expands both anteriorly and posteriorly at the distal half of the deltopectoral crest, due to a prominent posterior bulge; laterodistal corner of humerus forms an anteroposteriorly thin flange that does not expand as far anteriorly as the rest of the distal end; manual ungual I subrectangular in lateral view.
Comments- The holotype was discovered in 1996 and initially referred to Turiasaurus riodevensis in an abstract (Mateus, 2009) before being described as a new taxon (Mateus et al., 2014). However, the seven distinguishing characters listed by the latter authors are only determinable in the holotypes of each species. As Turiasaurus is only slightly later (Middle-Late Tithonian) and also from the Iberian peninsula, it seems plausible the taxa are synonymous, though this will require further comparable material to test.

Paul (1988) notes it is actually a proximal humerus. All modern authors have considered it an indeterminate sauropod, though as Barrett et al. (2002) note, the absence of a well-developed proximolateral humeral process excludes it from Somphospondyli. The Cretaceous age may indicate it is a neosauropod.

Neosauropoda indet. (Hu, 1964)
Turonian, Late Cretaceous
Tashuikou, Ulanhsuhi Formation, Inner Mongolia, China
Material- (IVPP V2884.X; paratype of Chilantaisaurus tashuikouensis) partial mid caudal centrum
Comments- Hu (1964) collected this in 1960, apparently associated with Chilantaisaurus. He said it was a carnosaurian middle caudal vertebra and "most probably belong to the same species." Noting only the subequal height and width (130 mm vs. 135 mm), his description was surpassed by Benson and Xu (2008) who stated it "has a stout and only weakly constricted centrum with subrectangular articular surfaces, and the broken attachments of the neural arch show that the latter was narrow." They said this suggests "that the centrum belongs to a sauropod and should be considered Sauropoda indet. (O.W.M.Rauhut, pers. comm.)". Indeed, Rauhut (2003) had previously stated one of the vertebrae with Chilantaisaurus tashuikouensis' specimen number "seems to represent a sauropod rather than a theropod."
