Kokybeisuch

Kokybeisuch is a genus of extinct crocodylomorphs that lived during the Late Jurassic epoch. Fossil remains of Kokybeisuch have been found in the Morrison Formation of North America. This ancient reptile is believed to have been a relatively small, terrestrial predator. Its exact phylogenetic position within the crocodylomorph lineage is still a subject of ongoing research, but it is generally considered to be a member of the Ziphosuchia or a closely related group.

The known fossils of Kokybeisuch are fragmentary, consisting mainly of skull elements and some postcranial material. These remains suggest a creature with a moderately elongated snout and sharp teeth, adapted for a diet of small vertebrates. The skeletal structure indicates it was likely an agile runner, contrasting with the more aquatic lifestyles of many later crocodylomorphs. The discovery of Kokybeisuch contributes to our understanding of the diversity and evolution of early crocodylomorphs during the Mesozoic Era, a period when these animals were diversifying into a wide array of forms before the dominance of true crocodiles. Further fossil discoveries are needed to fully elucidate the biology and evolutionary history of this intriguing extinct reptile.
