Postosuchus americanum (name meaning "American crocodile from Post") is a species of solitary bipedal rauisuchid reptile that originally lived in what is now North America during the Late Triassic, and was once extinct, but has since been brought back by SciiFii and now lives in the Triassic Dinosaurs section of Cretaceous Park located at Sacramento, California. Postosuchus americanum is a member of the clade Pseudosuchia, the lineage of archosaurs that includes modern crocodilians (the other main group of archosaurs is Avemetatarsalia, the lineage that includes non-avian dinosaurs and their descendants, birds). It is one of the apex Triassic predators found in Cretaceous Park, larger than the small dinosaur predators of its original time (such as Coelophysis). It is a hunter which once preyed on dicynodonts and many other creatures smaller than itself, but today, it is supplied by park staff with carrion and live food pigs to keep it healthy. The skeleton of Postosuchus americanum is large and robust with a deep skull and a long tail. The total body length is about 4 to 5 metres (13 to 16 ft). The extreme shortness of the forelimbs relative to the hind limbs, the very small hands, and the size of the vertebrae, allows Postosuchus americanum to move in a bipedal locomotion.
