 This feature is otherwise only known in dinosaurs (as well as a few other early crocodylomorphs) and is often regarded as a defining feature of that clade.Similarly, the femur of "Terrestrisuchus" has a distinct head that faces inwards towards the body, and fits into the hip socket at a right angle to the leg.This condition is described as "buttress-erect", and it is typical of dinosaurs and their close relatives but otherwise unheard of in pseudosuchians outside of basal crocodylomorphs.
