About Sebecus
Sebecus (meaning "Sobek" in Latin) is an extinct genus of sebecid crocodylomorph from Paleogene period of South America. Like other sebecosuchians, it was entirely terrestrial and carnivorous. The genus is currently represented by two species, the type S. icaeorhinus and S. ayrampu. Several other species have been referred to Sebecus, but were later reclassified as their own genera.
