Theriosuchus is an extinct genus of atoposaurid mesoeucrocodylian from the Late Jurassic-Early Cretaceous of Europe (Portugal and southern England) and Southeast Asia (Thailand), with fragmentary records from Middle Jurassic and Early Cretaceous sites in China, Morocco, and Scotland.[1]
Taxonomy
Three valid species are currently recognized: Theriosuchus pusillus from southern England,[2] T. guimarotae from Portugal,[1][3] and T. grandinaris from Thailand.[4] 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.[1]
Two species previously assigned to this genus, Theriosuchus ibericus[5] and T. symplesiodon,[6] have been re-assigned to the new genus Sabresuchus.[1]
Paleobiology
Fossils belonging to the genus are abundant at several European sites, namely Dorset, southern England.
