Thoracosaurus is an extinct genus of eusuchian crocodylomorph which existed during the Late Cretaceous and early Paleocene. The animal is usually regarded as a gavialoid crocodilian,[1] though the phylogenetic study published by Lee & Yates (2018) suggests that it might have been a non-crocodylian eusuchian.[2] The genus contains the species Thoracosaurus neocesariensis in North America [3] and Thoracosaurus isorhynchus (T. macrorhynchus being a junior synonym of T. isorhynchus)[4] in Europe. A number of species have been referred to this genus, but most are dubious.[1]
Thoracosaurus scanicus was a fairly large gavialoid, with a length of more than 4.4 m (14.4 ft) and a 55 cm skull.[5]
