Esipainotidae

Esipainotidae is a family of extinct ray-finned fish that lived during the Triassic period. Fossils attributed to this family have been found in various locations, including Europe. The exact phylogenetic placement of Esipainotidae within the broader context of Actinopterygii has been subject to research and revision.

These fish are characterized by specific skeletal features, particularly in their fin rays and skull morphology, which distinguish them from other Triassic fish groups. The limited fossil record means that much of our understanding of Esipainotidae relies on detailed analysis of these skeletal remains. Their ecological role and lifestyle are inferred from their anatomy and the paleoenvironment in which they are found, suggesting they were likely inhabitants of freshwater or brackish water environments. The study of Esipainotidae contributes to understanding the diversification of fish during the Mesozoic Era and the evolutionary pathways of ray-finned fishes. Further fossil discoveries and comparative anatomical studies continue to refine our knowledge of this extinct family.
