Plesiosuchus manselii
Taxonomy
Steneosaurus manselii was named by Hulke (1870). Its type specimen is NHMUK PV OR40103, a partial skeleton (incomplete skull and mandible), and it is a 3D body fossil.
It was synonymized subjectively with Dakosaurus maximus by Delair (1958); it was recombined as Dakosaurus manselii by Young et al. (2010), Bronzati et al. (2012); it was recombined as Plesiosuchus manselii by Owen (1884), Young et al. (2012), Young et al. (2013), Parrilla-Bel and Canudo (2015).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. T. Young et al. 2012 | Metriorhynchid crocodylomorph with the following unique combination of characters (autapomorphic characters are indicated by an asterisk): large robust teeth, with moderate to strong mediolateral compression; carinae formed by a keel and true microscopic denticles (microziphodonty, dimensions do not exceed 30 0mm); denticles are rectangular-shaped in lingual view*; tooth enamel ornamentation is largely inconspicuous, but there are apicobasally aligned ridges of low-relief*; the mesial margin of some teeth have a pronounced distal curvature*; separation between premaxilla and nasal approximately subequal to the midline length of the premaxilla; in dorsal view, the lateral margins of the prefrontals have an inflexion point directed posteriorly at an angle of approximately 70 degrees from the anteroposterior axis of the skull; palatines are strongly convex with a pronounced ridge along the midline*; in palatal view, the palatine width narrows anteriorly from the suborbital fenestrae to the midline (a distinct elongate triangular shape)*; the maxillopalatine suture midline terminus is level to the fourth maxillary alveolus*; quadrate distal articular surface is not separated into two condyles by a sulcus, and has only a very shallow depression at the centre*; mandibular symphysis long (9 out of 13 dentary teeth are adjacent to the symphysis). |
