kihawerenkaissa

kihawerenkaissa is a genus of extinct ray-finned fish that lived during the Late Cretaceous period. Fossil remains of kihawerenkaissa have been discovered in North America, primarily in the Judith River Formation of Montana. This genus is known for its unusual dentition, featuring large, conical teeth that suggest a predatory diet.

The genus was first described in 2005 based on a partial skeleton. Researchers have identified several key characteristics that distinguish kihawerenkaissa from other Cretaceous fish. These include specific features of its skull, vertebrae, and fin rays. The teeth are particularly notable for their size and arrangement, indicating an ability to grasp and consume relatively large prey.

While the exact ecological role of kihawerenkaissa is not fully understood, its predatory adaptations suggest it was an active hunter in its ancient freshwater or brackish water environment. The discovery of kihawerenkaissa contributes to our understanding of fish diversity during the Late Cretaceous, a period marked by significant evolutionary changes in aquatic ecosystems. Further fossil discoveries may provide more insights into the life and habits of this fascinating extinct fish.
