Pliosaurus sp. (Owen 1841)
OUMNH J.10454, a giant mandible
    = Stretosaurus macromerus Phillips 1871
Tarlo 1959
    = Pliosaurus macromerus Phillips 1871
Knutsen 2012
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)]
    = Pliosaurus ? rossicus Novozhilov 1948
Benson et al. 2013
"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"
