Albertosaurus Adult Juvenile (Digital Painting)

Young Albertosaurus are relatively large for juvenile animals, but their remains are still rare in the fossil record compared with adults. After just two years, juveniles were larger than any other predator in the region aside from adult Albertosaurus, and more fleet of foot than most of their prey animals.
Paleontologists have long debated whether Tyrannosaurus rex and its cousins, such as Albertosaurus, hunted alone or in groups. 
While most researchers believe the predators were lone wolves, so to speak, multiple Albertosaurusspecimens found in a single bone bed in Canada's Dry Island Buffalo Jump Provincial Park have led some to propose that tyrannosaurs were pack animals.
Similarly, pack hunting could explain how tyrannosaurs could kill hadrosaurs, which are almost as large as the predators, without sustaining horrific injuries.
That doesn't mean tyrannosaurs would have been friendly to one another. In fact, other fossils reveal that the dinosaurs liked to head-bite each other. But the tyrannosaurs may have stuck together to hunt because it increased their odds of survival.
