Crurotarsi is a group of archosauriformes that includes the archosaurs (represented today by crocodilians and birds) and the extinct, crocodile-like phytosaurs. The name is derived from the Latin word crus and the Greek word tarsos; it refers to the specialized articulation between crus and tarsus—specifically between fibula and calcaneum—present in the skeletons of suchians and phytosaurs, with a hemicylindrical condyle on the calcaneum articulating against fibula.
