Thoracosaurus is a medium-large gharial-like crocodile that lived during the late Cretaceous through to the Paleocene. Fossils of Thoracosaurus are usually associated with North American and European fossil deposits, but remains from other places such as India have also been reported. The sheer number of Thoracosaurus fossils seems to indicate that the genus was quite successful when compared to other similar creatures of the times and location that the genus existed.
