Paluxysuchus

Paluxysuchus is an extinct genus of neosuchian crocodyliform known from the Early Cretaceous Twin Mountains Formation (late Aptian stage) of north-central Texas. It contains a single species, Paluxysuchus newmani. Paluxysuchus is one of three crocodyliforms known from the Early Cretaceous of Texas, the others being Pachycheilosuchus and an unnamed species referred to as the "Glen Rose Form". Paluxysuchus has a long, flat skull that is probably transitional between the long and narrow skulls of many early neosuchians and the short and flat skulls of later neosuchians.

==Description== The skull of Paluxysuchus is long, flat, and shaped somewhat like a triangle when viewed from above. In the most complete fossil of Paluxysuchus, the skull is about long. The teeth at the tip of the snout are enlarged. A ridge of bone behind the eye socket called the postorbital process has an elongated prong that borders the side of the socket. This feature is seen in only two other crocodyliforms (the giant crocodyliform Sarcosuchus and an unnamed goniopholidid) but probably evolved independently in Paluxysuchus.
