edwardsorum

Edwardsorum is a genus of extinct ray-finned fish that lived during the Late Cretaceous period. Fossils of Edwardsorum have been found in marine sedimentary rocks, primarily in Europe. This genus is characterized by its distinct skeletal features, particularly the structure of its skull and fins.

The classification of Edwardsorum places it within the order of fossil fish known as Halecomorphi, a group that also includes modern bowfin. These ancient fish were likely inhabitants of shallow marine environments, suggesting they were adapted to coastal or estuarine conditions. Their diet is not definitively known, but based on the teeth and jaw structure of related species, they were likely piscivorous, feeding on smaller fish and invertebrates.

The discovery of Edwardsorum provides valuable insights into the diversity and evolution of fish during the Mesozoic Era. Studying its anatomy helps paleontologists understand the relationships between different fish groups and how they adapted to changing environmental conditions leading up to the K-Pg extinction event. Further research on new fossil discoveries and comparative anatomy continues to refine our understanding of this ancient lineage.
