Haematosaurus Explained

Haematosaurus is an extinct genus of teleosaurid thalattosuchian. Fossils have been found from Boulogne-sur-Mer in northern France of Jurassic age.^[1] It was originally thought to be a plesiosaur, and the type species was initially assigned to the genus Plesiosaurus in 1874, although it was later reassigned to the new genus in 1934.^{[2] [3]} It is now known to have been a marine crocodylomorph.^[4] Due to the fragmentary nature of the material associated with the genus, it is currently regarded as a nomen dubium.
