Sebecidae

Sebecidae is an extinct family of prehistoric terrestrial sebecosuchian crocodylomorphs. Sebecids were diverse, abundant and broadly distributed in South America (mostly in Argentina, Brazil and Bolivia) during the Cenozoic, until the Middle Miocene;[1] although it has been suggested that at least some forms could have survived until the Miocene-Pliocene boundary in Brazil.[2]

gollark: Do you actually know... Hebrew, or whatever that is?
gollark: I feel like I'm missing some sort of cultural context here.
gollark: Finally my years of German lessons come in slightly useful.
gollark: No offense meant, it just seems a weird combination of beliefs.
