Veyisidae

Veyisidae is a family of extinct teleost fish that lived during the Late Cretaceous period. Fossils of Veyisidae have been found in various locations, primarily in Europe and North Africa. These fish are characterized by their relatively small size and a body shape that suggests they were likely nektonic swimmers, capable of active movement in the water column.

The skeletal structure of Veyisidae exhibits several features common to modern ray-finned fish, but also possesses unique adaptations that distinguish them as a distinct evolutionary lineage. Their dentition suggests a diet that may have included small invertebrates or other small fish, although detailed dietary analyses are limited due to the scarcity and preservation state of fossil specimens.

The ecological role of Veyisidae within Late Cretaceous marine environments is not fully understood. However, their presence indicates a diverse ichthyofauna during this period. The fossil record for Veyisidae is relatively sparse, making detailed study challenging. Research continues to shed light on their relationships to other fish groups and their evolutionary history, though their exact placement within the teleost phylogeny remains a subject of ongoing investigation. The extinction of Veyisidae likely occurred at the end of the Cretaceous period, coinciding with the K-Pg extinction event.
