Crypioclidiis. and considerably more so than in Muraenosaurus and Tricleidus. Distally the paroccipital process bears a facet for union with the squamosal. The dentary (Figs 27, 37) is remarkably slender and lightly built, and in dorsal view the tooth-bearing area of spongy bone is predominant whilst the solid lamellar bone which strengthens the medial margin of the jaw ramus appears deficient by comparison with other genera ( Cryptoclidus, cf. Figs 3 and 37). The specimen has been eroded somewhat: the dorsal portions of the tooth sockets have been lost yet the ventral parts remain, and so the sockets appear as grooves which are orientated outwards and inclined slightly upwards. There are 34 well-preserved sockets on the right ramus, the most posterior of which blends into a space large enough to have held a further two sockets, thus making a total of 36; this is probably also the total for the left ramus. No remains of splenials could be identified on the medial surface. A small fragment of bone which represents part of the left premaxilla fudged from its position and close fit with the dentary) is compressed onto the dentary over the 3rd to 7th left tooth sockets. This fragment suggests that in life the premaxilla extended posteriorly at least to the level of the lowe
