Kuttaka

Kuttaka is a genus of extinct teleost fish that lived during the Eocene epoch, approximately 56 to 34 million years ago. Fossils of Kuttaka have been found in the Eocene deposits of the United States, particularly in the Green River Formation of Wyoming. These fossil fish are relatively small, with specimens typically measuring only a few centimeters in length.

The genus Kuttaka belongs to the family Catostomidae, which includes modern-day suckers. This classification is based on shared skeletal features, such as the structure of the mouth and the arrangement of fin rays. Kuttaka is thought to have inhabited freshwater environments, likely rivers and lakes, similar to its modern relatives.

The discovery of Kuttaka provides valuable insights into the evolution of catostomid fishes and the paleoecology of Eocene freshwater ecosystems. The fossils are often well-preserved, allowing scientists to study anatomical details and infer aspects of the fish's lifestyle, such as its diet and mode of locomotion. While Kuttaka itself is extinct, its evolutionary lineage has persisted to the present day in the form of extant sucker species. Research on Kuttaka continues to contribute to our understanding of ancient aquatic life and the broader history of vertebrate evolution.
