Vivass

Vivass is a genus of extinct teleost fish that lived during the Cretaceous period. These fish are known from fossil remains found in various locations, including Europe and North America. Vivass fossils are typically found in marine sedimentary rocks, indicating that these fish inhabited ancient seas.

The genus Vivass is characterized by a particular arrangement of bones in the skull and fins, which distinguishes it from other prehistoric fish groups. Like other teleosts, Vivass possessed a bony skeleton and typically had a streamlined body shape, adapted for swimming. Their diet likely consisted of smaller invertebrates or other small fish, though specific dietary habits are inferred from jaw structure and tooth morphology.

The discovery of Vivass fossils has contributed to our understanding of the evolution and diversity of ray-finned fishes during the Mesozoic Era. These ancient fish represent a part of the complex marine ecosystems that existed millions of years ago, before the major extinction event that marked the end of the Cretaceous period. Research on Vivass continues to refine our knowledge of early teleost diversification and the paleoenvironments they inhabited.
