OUMNH J.10454 is also referred here to P. macromerus based on its similarities in mandibular symphyseal tooth count with NHMUK 39362 [the new neotype of P. macromerus proposed by Knutsen (2012)] | ||||||||||

"We consider P. rossicus to be a valid species of Pliosaurus, based on the presence of a short symphysis containing only six alveoli, and provisionally refer OXFUM J.10454 to P. ?rossicus on the basis of this feature" | ||||||||||
