Ewinginsuch

Ewinginsuch is a genus of extinct ray-finned fish that lived during the Late Cretaceous period. Fossils of Ewinginsuch have been found in the Scollard Formation of Alberta, Canada. The genus was first described by Lance Grande and William K. Purdy in 2012. Only one species, Ewinginsuch albertensis, is currently known.

The remains of Ewinginsuch suggest it was a relatively small fish, with an estimated length of around 10 centimeters. It possessed a deep body and a protrusible jaw, adaptations that likely aided in capturing small prey. Its dentition indicates a diet of small invertebrates and possibly other small fish. Ewinginsuch is classified within the order Acipenseriformes, which includes modern sturgeons and paddlefishes. This placement suggests a shared ancestry with these well-known groups. The discovery of Ewinginsuch provides valuable insights into the diversity and evolution of freshwater fish ecosystems in North America during the Cretaceous. Its presence in the Scollard Formation, a deposit known for its rich fossil record of dinosaurs and other vertebrates, highlights the complex ecological interactions of the time. Further research on its skeletal structure and phylogenetic relationships continues to refine our understanding of this ancient fish.
