Sebecidae is an extinct family of prehistoric terrestrial sebecosuchian crocodylomorphs. The oldest known member of the group is Ogresuchus furatus known from the Upper Cretaceous (Maastrichtian) Tremp Formation (Spain).[1] Sebecids were diverse, abundant and broadly distributed in South America (mostly in Argentina, Brazil and Bolivia) during the Cenozoic, until the Middle Miocene;[2] although it has been suggested that at least some forms could have survived until the Miocene-Pliocene boundary in Brazil.[3]

This group included many medium- and large-sized genera, from Sebecus to a giant indeterminate unnamed species from the Miocene.[4]
