Taxonomy

Three valid species are currently recognized: Theriosuchus pusillus from southern England,[4] T. grandinaris from Thailand,[5] and T. morrisonensis from the Morrison Formation of North America.[6] 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.[3]
Two species previously assigned to this genus, Theriosuchus ibericus[7] and T. symplesiodon,[8] have been reassigned to the new genus Sabresuchus.[3] On the other hand, Theriosuchus guimarotae from Portugal[9] has been reassigned to Knoetschkesuchus.[10]
