Text-fig. 8. a. Shell belonging to one flank of the conch a horizontally bedded individual with sveral large oysters attached to its underside indicating that the shell was either originally vertical or was flipped from one surface to the other by turbulance. Approximately 300 mm across. b. Crushed individual showing oysters encrusting both flanks of the conch. 250 mm in diameter. c. Wave-worn conch showing oysters attached to the umbilicus, the venter and possibly the inside of the body-chamber. Tape measure for scale. d.

Text-fig. 9. a. Shorn-off, vertically embedded conch surrounded by layer of crinoid debris at level of planation of shell and with some debris within the conch at this level. Lateral width of body-chamber 80 mm. b. Example of ammonite that occurs rarely in the Main Cenoceras Bed. Note the poorly defined shell particularly on the outer whorl, suggesting partial dissolution.

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.
