"Thoracosaurus is an enormous marine crocodylomorph that lived in the shallow seas of both North America and Europe during the Cretaceous and Paleocene. With its long, thin snout and conical teeth suited for snatching fish, this animal is similar in appearance to the modern gharial of India. It also resembles the coeval Champsosaurus in this regard, but is unrelated to both. Instead Thoracosaurus is a Eusuchian, just outside the group including living crocodilians. Thoracosaurus is the rarest of the Hell Creek Eusuchians and also the largest, with some specimens reaching up to 9 meters in length."

Saurian: A Field Guide to Hell Creek

Thoracosaurus was a genus of crocodylomorph that existed during the Late Cretaceous and Early Paleocene. It was between four and five meters in length, or more depending of the species, as some could reach exceeding lengths of eight meters, being the biggest crocodylomorph known from Hell Creek Formation. It seems to have lived in saltwater environments.

It contains the species Thoracosaurus neocesariensis in North America and Thoracosaurus isorhynchus in Europe. A number of species have been referred to this genus, but most are dubious, and only three are considered as valid for now.

It likely would have lived like a modern gharial based on the similar jaws. Gharials catch fish by waiting for them to pass by and catching them by quickly whipping their heads sideways. Although, despite Thoracosaurus has been largely considered a gavialoid, very recent studies seem to suggest that the simillarities between Thoracosaurus and gharials are just a product of convergent evolution, and that Thoracosaurus wasn't actually a crocodilian as previously expected, being a stem-crocodilian instead, more related to the contemporaneous Borealosuchus, also believed to be a stem-crocodilian, under the same study.

In Saurian Edit

Thoracosaurus is expected to appear in Saurian, as revealed in a livestream[1]. It is dark brown with a tan belly and striping on the sides.

Behind the scenesEdit

The model of Thoracosaurus was sculpted by Jake Baardse.[1]

The color seems to be based on its relative, the false gharial.
