Thallatocherius

Thallatocherius is a genus of extinct marine reptiles belonging to the order Plesiosauria. These marine reptiles lived during the Late Cretaceous period. Fossils attributed to Thallatocherius have been discovered in various locations, primarily in Europe. The genus is characterized by specific anatomical features of its skull and vertebral column, which distinguish it from other plesiosaurian groups.

As a plesiosaur, Thallatocherius was a marine predator. Its diet likely consisted of fish and other small marine organisms. The general body plan of Thallatocherius would have been typical of plesiosaurs, featuring a long neck, a broad body, and four paddle-like limbs adapted for swimming. The precise size and appearance of Thallatocherius are based on the fragmented fossil evidence available.

The classification of Thallatocherius has been subject to revision over time as new discoveries are made and existing specimens are re-examined. Its phylogenetic relationships within Plesiosauria are important for understanding the evolution and diversity of these ancient marine reptiles. Further research and the discovery of more complete fossil remains are crucial for a more comprehensive understanding of Thallatocherius and its place in the marine ecosystems of the Cretaceous.
