Calsoyasuchus (meaning "[Dr. Kyril] Calsoyas' crocodile") is a genus of crocodylomorph[1] that lived in the Early Jurassic. Its fossilized remains were found in the Sinemurian-Pliensbachian-age Kayenta Formation on Navajo Nation land in Coconino County, Arizona, United States. Formally described as C. valliceps, it is known from a single incomplete skull which is unusually derived for such an early crocodile relative. This genus was described in 2002 by Ronald Tykoski and colleagues; the specific name means "valley head" and refers to a deep groove along the midline of the nasal bones and frontal bones.[2] It has often been interpreted as the earliest diverging member of Goniopholididae, but other studies have recovered it in various other positions.
