Sebecidae is an extinct family of prehistoric terrestrial sebecosuchian crocodylomorphs, known from the Late Cretaceous and Cenozoic of Europe and South America. They were the latest surviving group of non-crocodilian crocodylomorphs.

The oldest known member of the group is Ogresuchus furatus known from the Upper Cretaceous (Maastrichtian) Tremp Formation (Spain).[2] Other records of the group are known from the Eocene of Europe.[3] Sebecids were diverse, abundant and broadly distributed in South America (mostly in Argentina, Brazil and Bolivia) during the Cenozoic, from the Paleocene until the Middle Miocene;[4] although it has been suggested that at least some forms could have survived until the Miocene-Pliocene boundary in Brazil.[5]
This group included many medium- and large-sized genera, from Sebecus to the giant 6-metre-long (20 ft) Barinasuchus from the Miocene.[6] They are thought to have served as apex terrestrial predators of their ecosystems.[7]
Phylogeny
editJuan Leardi and colleagues in 2024 defined Sebecidae in PhyloCode as "the least inclusive clade containing Sebecus icaeorhinus, Bretesuchus bonapartei, Barinasuchus arveloi, and Sahitisuchus fluminensis".[8] The following cladogram simplified after Diego Pol and Jaime E. Powell (2011).[4]
