Pliosauroidea: Classification, Large pliosauroids & Overview

Pliosauroidea is an extinct clade of plesiosaurs, known from the latest Triassic to early Late Cretaceous. They are best known for the subclade Thalassophonea, which contained crocodile-like short-necked forms with large heads and massive toothed jaws, commonly known as pliosaurs. More primitive non-thalassophonean pliosauroids resembled plesiosaurs in…
