Bitidenas

Bitidenas is a genus of extinct ray-finned fish that lived during the Late Cretaceous period. Fossils of bitidenas have been found in marine deposits, primarily in Europe. The genus is characterized by its unique dental arrangement, with two rows of teeth on the upper jaw. These teeth were likely adapted for crushing or grasping prey. Bitidenas belongs to the order Clupeiformes, which includes modern-day herrings and sardines. This suggests that bitidenas may have shared similar ecological roles, possibly feeding on small invertebrates or plankton. The fossil record indicates that bitidenas was a relatively small fish, with most specimens measuring only a few centimeters in length. The precise evolutionary relationships of bitidenas within Clupeiformes are still a subject of ongoing research. Its discovery provides valuable insights into the diversity of marine life during the Cretaceous and contributes to our understanding of fish evolution.
