Igarassus
Igarassus is a genus of extinct marine reptiles belonging to the order Plesiosauria. These animals lived during the Early Cretaceous period, approximately 130 to 125 million years ago. Fossils attributed to Igarassus have been discovered in South America, primarily in Brazil. The genus is known from a limited number of fossil specimens, which has made its precise taxonomic placement and detailed understanding of its biology challenging for paleontologists.
The anatomy of Igarassus suggests it was a relatively small to medium-sized plesiosaur. Like other plesiosaurs,
