Daspletosaurus

Daspletosaurus (name meaning "frightful lizard") is a genus of tyrannosaurid theropod dinosaur that lived in North America during the Late Cretaceous period.

Description
Daspletosaurus was a 8-9 meters long predator that was powerfully built. It was stocky and had a muscular S-shaped neck and relatively small arms. Powerful jaw and neck muscles allowed it to use its banana-sized teeth to tear into its victims' flesh. If its prey were to run, its powerful legs would have helped it keep up. However, if the opportunity presents itself, Daspletosaurus would scavenge carcasses.

Cannibalism
Daspletosaurus and the rest of the tyrannosaurs may have been cannibals, as suggested by tooth marks found on some of their fossilized bones.

Last Killers
A Daspletosaurus tries to kill a Chasmosaurus, but is unsuccessful. However, the rest of the pack, consisting of juveniles and adults, appear and helps bring down the Chasmosaurus. Later in the episode, the pack of Daspletosaurus attacks a herd of Centrosaurus, causing them to stampede and eventually drown in a flooded river. Later, when the river dries up during the dry season, the Daspletosaurus begin scavenging the rotting carcasses. One scavenging Daspletosaurus spots a small pack of Troodon scavenging on a carcass and scares them away before stealing the carcass for itself.
