Albertosaurus
When the first Albertosaurus was spotted in Alberta, Canada, palaeontologists had no idea how interesting and controversial this relative of the Tyrannosaurus rex would prove to be.
Close family
Most palaeontologists believe that the large meat-eating dinosaurs live and hunt alone. However, Albertosaurus might be the exception to the rule. The remains of nine Albertosaurus have been found together. What’s more, the dinosaurs appear to be of different ages. Does Albertosaurus believe that the family that hunts together stays together? This means that the other tyrannosaurs might also live in family groups, but we just haven’t seen any evidence of this yet.
Mistaken identity
A palaeontologist’s job is never easy: there’s now debate about exactly how many Albertosaurus have been found. Some albertosaurs may actually be a different dinosaur altogether - another branch of the tyrannosaur family called Gorgosaurus (GOR-go-SORE-us). What this proves is that the tyrannosaur family is a big one and they all have a strong family resemblance - powerful legs, short arms, a big head and scary teeth.
