Valvasain

Valvasain is a genus of extinct marine reptiles belonging to the family Pliosauridae, a group of short-necked plesiosaurs. These large predators roamed the oceans during the Late Jurassic period, approximately 160 to 150 million years ago. Fossils of Valvasain have been discovered in various locations, including Europe.

The genus Valvasain is characterized by specific anatomical features, particularly in its skull and dentition, which distinguish it from other pliosaurs. Like other pliosaurs, Valvasain possessed a powerful build with four large flippers adapted for swimming. Its diet likely consisted of fish and other marine animals.

The classification of Valvasain has been subject to scientific study and debate, with ongoing research refining our understanding of its evolutionary relationships within the Pliosauridae family. The discovery and analysis of Valvasain fossils contribute to our knowledge of marine ecosystems and the diversity of prehistoric life during the Jurassic.
