Description
The poll has spoken, and the crocodile has won.

Thoracosaurus was a genus of either gavialoid eusuchian crocodiles, or possibly just outside crocodylia, mostly known from the United States from the species Thoracosaurus neocesariensis. The size of this species is probably overestimated in many sources, due to the proportionally huge head, which leads to larger size estimates based on the skull than it would do otherwise.

Remains from the Maastricht formation have been tentatively referred to this crocodile, however, their incomplete and fragmentary nature makes a referral to Thoracosaurus neocesariensis uncertain. A jaw belonging to a second species of Thoracosaurus, Thoracosaurus macrorhynchus, has also been found in the Maastricht formation. However, it is uncertain if this jaw was truly found here, or somewhere else. Mislabeling fossils used to be more common back when it was found.

The postcranial remains from Maastricht indicate two individuals, one roughly 3 meters in length and the other exceeding 4 meters, based on modern false gharials. The latter of which I chose to depict in my drawing. Some remains from Hell Creek, North America, suggest that it might have grown to much larger sizes.

Thoracosaurus likely spent much time out at sea, and crossed large bodies of salt water regularly, as is indicated by it´s very wide geographic distribution. The slender jaws of this crocodile likely limited it to relatively small prey, and it likely focussed on fish like it´s modern relatives, Tomistoma gharials. However, even Tomistoma have been recorded killing rather large, terrestrial prey, so it may have hunted man-sized animals as well from time to time.

In the Maastricht seas, Thoracosaurus faced fierce competition from the larger, faster and more aquatically adept mosasaurids. Despite this, it thrived here and survived the K-Pg impact and kept existing for another few million years, unlike the mosasaurids.
