However, we now know that it was much more likely to have been an obligate biped, only able to walk on its hind legs, like most theropod dinosaurs. Because of this, Postosuchus was often depicted as being able to walk on four or two legs when alive. An example of this would be a the pelvis, hand, and toe bones, which would later be found to have really belonged to Shuvosaurus.

Because the first group of specimens' bones were not always found articulated, and often times among those of other species, early Postosuchus skeletal reconstructions accidentally were partially made of bones from other kinds of animals. Postosuchus has gone through a few makeovers over the years since it was discovered.

Postosuchus life reconstruction in watercolors by Christopher DiPiazza. The species name is in honor of the Kirkpatrrick family, who helped in Postosuchus' excavation. The genus name, Postosuchus, translates to 'Post Crocodile', in reference to Post Town, Texas, where the first Postosuchus bones were unearthed. It was one of the largest animals in its environment, with adults measuring between thirteen and fifteen feet long from snout to tail, and ate meat, probably hunting many of the other Triassic animals from the area, including fellow pseudosuchians, Shuvosaurus and Desmatosuchus, and the dinosaur, Coelophysis. Postosuchus was a pseudosuchian archosaur, more closely related to crocodilians than to dinosaurs, that lived in what is now the Southern United States, specifically New Mexico, Arizona, Texas, and as far east as North Carolina, during the Triassic Period, between 221 and 203 million years ago. This creature also helps teach us it's okay to change our perceptions as we learn new things, especially in science.

This week we will be checking out a beast that shows us that evolution is capable of truly amazing things and how deceiving looks can really be.
