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]
The following cladogram simplified after Diego Pol and Jaime E. Powell (2011). [4]
