brevidens

Brevidens is a genus of extinct ray-finned fish that lived during the Late Jurassic period. Fossils of brevidens have been found in Europe. This genus is characterized by its short, deep body and the presence of large, robust teeth. These teeth suggest that brevidens was a predator, likely feeding on smaller fish or invertebrates. The skeletal structure of brevidens indicates it was a relatively slow-swimming fish, possibly inhabiting bottom or mid-water environments.

The classification of brevidens has been debated among paleontologists, with some placing it within the order Semionotiformes and others considering it part of a more generalized group of basal actinopterygians. Its distinctive features, particularly its dentition, set it apart from other known Jurassic fish. The discovery of brevidens fossils contributes to our understanding of fish diversity and evolution during the Mesozoic Era. Further research into its anatomy and paleoecology is ongoing.
