Theriosuchus is an extinct genusofatoposaurid neosuchian from Late JurassictoEarly CretaceousofEurope (Hungary & southern England), Southeast Asia (Thailand) and western North America (Wyoming), with fragmentary records from Middle Jurassic and Early Cretaceous sites in China, Morocco, and Scotland.^[2]

Taxonomy[edit]

Skull elements of T. pusillus

Three valid species are currently recognized: Theriosuchus pusillus from southern England,^[3] T. grandinaris from Thailand,^[4] and T. morrisonensis from the Morrison Formation of North America.^[5] Theriosuchus was previously assigned to Atoposauridae, but a 2016 cladistic analysis recovered it as a neosuchian more closely related to members of the family Paralligatoridae than to atoposaurids.^[2]

Two species previously assigned to this genus, Theriosuchus ibericus^[6] and T. symplesiodon,^[7] have been reassigned to the new genus Sabresuchus.^[2] On the other hand, Theriosuchus guimarotae from Portugal^[8] has been reassigned to Knoetschkesuchus.^[9]
