Peloneustes Lydekker, 1889
Peloneustes is one of several pliosaur genera from the Oxford Clay Formation in the UK. It is one of the better known pliosaurs from this horizon, represented by 12 nealy complete skulls and several skeletons. It is also the most abundant pliosaur from the Peterborough Member of the Formation (Ketchum and Benson, 2011). Peloneustes is characterised by an elongate mandibular symphysis which contains 13-15 pairs of teeth, but this number varies within the species (Tarlo, 1960; Ketchum and Benson, 2011).
