Sebecus

The name Sebecus comes from the Latinization of the crocodile god Sobek of Ancient Egypt. Sobek was considered the alternative because Champsa was claimed by a Greek historian to be the Egyptian word for crocodile and the Greek word for crocodile is suchus.

Unlike modern crocodilians, Sebecus has a deep, narrow snout. The nares, or nostrils, open anteriorly at the tip of the snout. While most crocodilians have flat skulls that are raised near the eyes and postorbital region behind the eyes, the skull of Sebecus is essentially level.

Laterally compressed, or ziphodont teeth, are characteristic of Sebecus and other sebecosuchians. Although the teeth vary in size, they are homodont, having a similar shape throughout the jaw. At the tips of the upper and lower jaws, the teeth are rounder in cross-section. The fourth dentary tooth is raised in the lower jaw to form an effective canine. The foremost teeth of the lower jaw are much smaller and lower than the fourth tooth. At the tip of the jaw the first dentary tooth is procumbent, or directed forward. The teeth of the upper and lower jaws form an alternate pattern to allow the jaw to close tightly. A notch is present between the maxilla and premaxilla bones of the upper jaw, accommodating the fourth dentary tooth when the jaw is closed. The procumbent first dentary teeth fit between the first and second premaxillary teeth. This close fit allows the serrated edges of the teeth to shear with one another.

The articulation between the articular and quadrate bones at the jaw joint is well developed. Along with the broad downturned "wings" formed by the pterygoid and ectopterygoid bones at the bottom of the skull, this articulation restricts the jaw to up-and-down movement. The jaw movement and close shearing of the teeth suggest that Sebecus was carnivorous. Its compressed, blade-like teeth would have been well-suited for cutting meat. In contrast, living crocodilians have circular, widely spaced teeth and usually consume their food in large pieces. Sebecus likely consumed food in a manner more similar to theropod dinosaurs than living crocodilians.

Coming like living crocodilians, the depressor muscle of Sebecus was relatively underdeveloped. Therefore, while the closure of the jaws would have been very strong, the ability to open the jaws would be much weaker.

‬Sebecus would‭ ‬have been predators of other similarly sized animals,‭ ‬but unlike crocodiles that we know today,‭ ‬Sebecus would have been more terrestrial and hunting on the land.‭ ‬Details of the anatomy such as longer legs and eyes that are on the sides of the head rather than orientated to look up all support this conclusion.‭ ‬The snout of Sebecus was deep,‭ ‬indicating longer jaw closing muscles that in turn suggest that‭ ‬had a particularly strong bite.‭ 

The teeth of Sebecus have also been noted to be similar to the teeth of the earlier tyrannosaurid dinosaurs.‭ ‬These teeth had fairly blunt tips but were strongly serrated,‭ ‬with the serrations adapted for tearing up the preys muscle fibres.‭ ‬Combined with the extra strong jaw closing muscles and Sebecus may have hunted animals that had notably tough hides,‭ ‬possibly even crunching through bones.

This suggested that it was a carnivore that ate most of its kill when it made one. It might also hint at a life more suited to scavenging but scavengers don't need large, serrated teeth for eating rotting flesh so it was most likely an active carnivore.

The Sebecus is a stamina-draining attack and high power can make its attack fatal. Beware traveling in murky or dark parts of the swamp, or at night, as the cover may allow the sebecid to sneak close without you noticing and open you up to a surprise pounce. The Sebecus will swim around in the swamp regions, attacking different creatures of prey when entering the territory.

This species of sebecid was endemic in Argentina and nearby countries at ‬Casamayor Formation,‭ at ‬Sarmiento Formation in the Eocene.

Sebecus is one of the most powerful tames for beginners, despite being small and serves as a decent guardian to yourself and your herd, and having a pack of 2-3 can safeguard you from predators like wolverines and wolves.

Quickly knock it unconscious (use tranquilizer arrows, clubs, or anything else that can knock dinos unconscious) before it reaches water where it will gain the upper hand.
