Figure 8 in Cranial anatomy of Shunosaurus, a basal sauropod dinosaur from the Middle Jurassic of China

Figure 9 in Cranial anatomy of Shunosaurus, a basal sauropod dinosaur from the Middle Jurassic of China
Figure 9. Maxillary dentition and tooth wear of Shunosaurus lii (ZG65430). A, sagittal cross-section of a maxillary tooth in alveolus showing the relative depth of the lingual and labial walls; the missing interdental plate gives a pleurodont-like tooth implantation. B, the same jaw section when the interdental plate is restored in place, showing typical thecodont implantation. C, lingual view of the left maxilla showing tooth wear facets, replacing teeth, and interdental plates.
Figure 11 in Sauropod dinosaur phylogeny: critique and cladistic analysis
Figure 11. Upchurch (1998) continued. A, 50% majority-rule consensus of 15 trees produced when all characters are left unordered. B, most parsimonious tree when only characters C75−C79 are left unordered. Dashed lines indicate nodes that collapse in a 50% majority-rule consensus of trees two steps longer than the most parsimonious tree.
Figure 8 in Sauropod dinosaur phylogeny: critique and cladistic analysis
Figure 8. Minimum implied gap (MIG) predicted by the topologies of Wilson & Sereno (1998), left, and Upchurch (1998), right. Grey bars indicate missing lineages as implied by sister-taxon relationships. The dashed bar denotes an missing interval for Diplodocoidea that is implied by the late appearance of the controversial species Antarctosaurus wichmannianus (Huene, 1929), here regarded as a rebbachisaurid (see Table 13). Timescale based on Harland et al. (1990).
Figure 1 in Sauropod dinosaur phylogeny: critique and cladistic analysis
Figure 1. Silhouette skeletal reconstruction of Dicraeosaurus hansemanni in right lateral view. The reconstruction is based on a partial skeleton (HMN skeleton m), which includes a partially articulated vertebral series from the axis to the 18th caudal vertebra (including ribs and chevrons), a pelvis, and a hindlimb lacking the pes (Janensch, 1929b; Heinrich, 1999: fig. 19). Elongate, biconvex distal caudal centra were collected at sites s and dd, but the length of this series is unknown (McIntosh, 1990: 392). The presence of a 'whiplash' tail of 20 or more elongate, biconvex caudal centra is equivocal for Dicraeosaurus (Wilson et al., 1999: 594). A 'whiplash' of intermediate length has been reconstructed here. The forelimb was based on a second specimen (HMN skeleton o) preserving a scapula, coracoid, humerus, and ulna in association with caudal vertebrae, a pelvis, and a partial hindlimb (Heinrich, 1999: fig. 6). Missing elements of the manus and pes were based on those of Apatosaurus (Gilmore, 1936); missing cranial elements were based on Diplodocus (Wilson & Sereno, 1998: fig. 6A).
Figure 5 in Sauropod dinosaur phylogeny: critique and cladistic analysis
Figure 5. Tail specializations in sauropod dinosaurs. A, bony tail club of Shunosaurus; B, short, biconvex distal caudal vertebrae of a unnamed titanosaur from Argentina; C, 'whiplash' tail vertebrae of Diplodocus. A–C modified from Dong et al. (1989: fig. 1), Wilson et al. (1999: fig. 2), and Holland (1906: fig. 29), respectively. Scale bars = 10 cm.
Figure 13 in Sauropod dinosaur phylogeny: critique and cladistic analysis
Figure 13. Phylogenetic relationships of Sauropoda proposed in this analysis (matrix in Appendix 1). A, most parsimonious tree. B, 50% majority-rule consensus of 1443 trees five steps longer than the most parsimonious tree produced by a pruned matrix. Percentages indicate frequency of preservation of nodes among trees.
Figure 7 in Sauropod dinosaur phylogeny: critique and cladistic analysis
Figure 7. Strict (left) and 50% majority-rule (right) consenses of the five recent cladistic hypotheses shown in Figure 6. Dashed line indicates increased resolution after rescoring two characters in the data matrix of Calvo & Salgado (1995).
Figure 2 in Sauropod dinosaur phylogeny: critique and cladistic analysis
Figure 2. Temporal distribution and relationships of major lineages of dinosaurs during the Triassic and Jurassic. The asterisked grey bar represents the ghost lineage preceding the first appearance of sauropods in the fossil record. The diagnostic features of Sauropoda evolved during this implied 15–25 million year interval. Icons from Wilson & Sereno (1998) and Sereno (1999); timescale based on Harland et al. (1990).
Figure 6 in Sauropod dinosaur phylogeny: critique and cladistic analysis
Figure 6. Five recent cladistic hypotheses of sauropod relationships. Each has been simplified for ease of comparison and to reflect higher-level groupings.
Figure 10 in Sauropod dinosaur phylogeny: critique and cladistic analysis
Figure 10. Upchurch (1998). A, fully resolved most parsimonious tree; B, most parsimonious tree produced with taxa pruned to match those of Upchurch (1995). Dashed lines indicate nodes that collapse in a 50% majority-rule consensus of trees two steps longer than the most parsimonious tree.

Figure 24 in The 'fabrosaurid' ornithischian dinosaurs of the Upper Elliot Formation (Lower Jurassic) of South Africa and Lesotho
Figure 24. Right ilia of Lesothosaurus diagnosticus (A: BMNH RUB17), Scelidosaurus harrisoni (B: BMNH R6704) and Hypsilophodon foxii (C: BMNH R196). Note the plesiomorphic retention of a supraacetabular flange and a ventral flange backing the acetabulum in Lesothosaurus and Scelidosaurus; both these features are lost in Hypsilophodon. The pubic peduncle is elongate, and larger than the ischiadic peduncle, in both Lesothosaurus and Scelidosaurus. The brevis shelf angles ventromedially in Lesothosaurus and Scelidosaurus and is visible in lateral view, creating a deep postacetabular portion of the ilium. The brevis shelf of Hypsilophodon is horizontal. Abbreviations: bs, brevis shelf; ilpp, peduncle; ilisp, ischiadic peduncle; saf, supraacetabular flange; vf, ventral flange partially backing the acetabulum.
