Kayentasuchus is a genus of small sphenosuchian crocodilomorph that lived in the south-west of the USA during the early Jurassic. Overall Kayentasuchus is noted for having a gracile build with slender limbs. The front of the skull is narrow with the lower jaw curved upwards, indicating that Kayentasuchus may have been quite specialised in their feeding habits.
