I wonder if there has ever been a fossil of a creature that died asperating on something that was aspirating on something else. Polcyn (2008) reported markedly reduced bony labyrinths in mosasaurs, compared with terrestrial varanoids, yet a recent quantitative analysis on Plioplatecarpus bony labyrinth (Cuthbertson et al., 2015) failed to find statistical support for shorter semicircular canals than in extant squamates, proportional to the length of the skull. This specimen led to a re-evaluation of the Platecarpus was a medium-sized mosasaur with long, narrow jaws lined with sharp, pointy teeth.

Phylogenetic analysis incorporating 97 morphological characters and 17 ingroup taxa indicates that (1) Ectenosaurus clidastoides is the basal-most member within the Plioplatecarpinae; (2) Platecarpus planifrons is generically distinct from P. tympaniticus; (3) Latoplatecarpus willistoni, gen. et sp.

The large head had huge jaws, up to 4 ft (1.2 m long) with many teeth. Plioplatecarpus were an exception rather than the rule. It is concluded that both an anterior migration of the rib cage and an increasing regionalization within the dorsal vertebral series are key features contributing to formation of a streamlined body profile in P. tympaniticus, and probably in many other hydropedal members of mosasaurs.
