Albertosaurus appeared in Episode 6.[77-72] [3 OS]
Albertosaurus was an earlier cousin of Tyrannosaurus. Although smaller than the T. rex, this tyrannosaurid dinosaur lived a few million years earlier than Tyrannosaurus and was a carnivore as well.
Albertosaurus was up to 30-33 ft. (10 m.) from head to toe, stood about 9-11 ft. (3 m.) tall at the hips, and weigh as much as 3 tons.Albertosaurus had a long tail that provided the required balance and it even aided the dinosaur while turning. Albertosaurus preyed on Parasaurolophus and brought them down by hunting in cooperative packs. However, it had a rivalry with the giant crocodilian Deinosuchus, which was considered to be a top predator of that time period.
A pair of Albertosaurus was seen roaring at a pair of Parasaurolophus and Nigel Marven. As the Parasaurolophus escaped, the pair concentrated on Nigel. As Nigel powered up his jeep, the pair pursued him. Despite going over 30 mph, the Albertosaurus managed to keep up. Shortly after, they stopped.
A pack of Albertosaurus was later seen confronting a group of Deinosuchus over a Parasaurolophus carcass. After they fought over the kill, the Albertosaurus lost and the kill now belonged to the Deinosuchus.
