Plesiosuchus

Originally thought to be a skull of a pliosaur,‭ ‬the Plesiosuchus holotype remains were originally credited as a species of Steneosaurus by John Hulke in‭ ‬1870‭ ‬.‭ ‬Steneosaurus is a genus of teleosaurid crocodile,‭ ‬a type believed to be common in coastal locations such as estuaries where they fed upon fish.‭ ‬Later study though identified the remains as actually belonging to a metriorhynchid crocodile,‭ ‬a different type of crocodile that has greater adaptations towards living most of its life in the sea.‭ ‬As such in‭ ‬1884,‭ ‬Richard Owen established the genus Plesiosuchus from the remains.‭ ‬In the past some studies have considered Plesiosuchus to represent a species of Dakosaurus‭; ‬however the most recent studies at the time of writing have concluded that Plesiosuchus is indeed a distinct genus.
