The Sebecosuchians were a unique clade of Crocodyliformes that were known for their terrestrial habits, ziphodont teeth (d-shaped, serrated, and laterally compressed; good for cutting and bleeding) and almost theropod-like skulls. They were the only other Crocodyliformes to survive the K-T extinction; with their evolutionary history going as far back as the Middle Jurassic, right up until the Middle Miocene (some studies suggest they may have even survived to the Earliest Pliocene). Sebecus is a typical member of this group and the namesake of the whole clade and its immediate family (The Sebecidae). It was a middle sized terrestrial reptile that roamed the forests of the Early-Middle Eocene of Argentina, and one of the apex land predators of its environment. The name is a latinized reference to Sobek; the Crocodile-headed god of ancient Egypt.
