Sabresuchus is an extinct genus of neosuchian crocodyliform from the Cretaceous of Europe.^[1] The name is derived from 'Sabre' in reference to the enlarged and curved fifth maxillary tooth, and 'suchus' from the Ancient Greek for crocodile.^[2]

Taxonomy

Two valid species are currently recognized: Sabresuchus ibericus from eastern Spain, and Sabresuchus sympiestodon from Romania,.^[2] Both species were previously assigned under the genus Theriosuchus, as T. ibericus^[3] and T. sympiestodon^[4] respectively. A 2016 cladistic analysis recovered it as a neosuchian more closely related to members of the family Paralligatoridae than to atoposaurids.^[2]
