|---|---|---|
| A. R. I. Cruickshank and R. E. Fordyce 2002 | "Large cryptoclidid plesiosauroid differing from described cryptoclidids in the following features: jugal bar exceptionally deep; jugal apparently large and subtriangular; lack of cheek bar excavation; orbit anteriorly placed; postorbital region relatively long; tooth count of premaxilla 7, maxilla 36+, dentary 42+; cervical vertebral count 43; anterior cervical centra widened and bilobed in anterior view, with lobes separated by ventral notch. Differs from Tricleidus in lack of cheek bar excavation; deep cheek bar; increased number of premaxillary and maxillary teeth; highly regular teeth with reduced ornament; increased number of cervical vertebrae; large body size. Further, differs from Morturneria and Aristonectes in having fewer teeth; from Morturneria in apparently lacking extremely long pineal opening and lacking far forward development of parietals; and from Aristonectes in shallower excavation of lower margin of cheek bar, and fewer premaxillary and dentary teeth." |
