Sebecosuchians were a successful group of predatory Notosuchians mostly native to the southern continents (with some notable exceptions). This lineage of hypercarnivorous terrestrial predators thrived in Late Cretaceous and Cenozoic South America, successfully competing with medium sized Theropod dinosaurs in many cases. Possessing xiphodont teeth, boxy laterally compressed skulls and erect limbs, Sebecosuchians spent their entire lives away from water.

It was previously assumed that these animals were endemic to South America but later finds have since disproven this, with species native to Africa, Europe and possibly South Asia as well. First appearing in the fossil record about 85 million years ago, phylogenetic studies have suggested that Sebecosuchians probably diverged during the Middle Jurassic in Gondwana. Surviving the KPG extinction event, these animals produced large and powerful forms in Miocene South America, with the 6m genus Barinasuchus being among the most massive terrestrial predators of the Cenozoic. Sebecosuchians died out during the later Miocene as their island continent began to cool and develop more arid, open conditions, with preferred Notoungulate prey becoming rarer and less diverse.
