Albertosaurus
Albertosaurus (al-BURR-to-SORE-us) is the species name
for several species of tyrannosaurids that looked similar
to Tyrannosaurus rex, but were rather smaller.Albertosaurus
also tended to be less massive than T. rex, as fine as
its contemporary Daspletosaurus (also a tyrannosaurid
of similar length).
The co-existence of these two animals have lead to the proposal that they were
specialized
for killing different kinds of prey: Albertosaurus may have
went after fleeter prey, like duck-billed dinosaurs and ornithomimids,
while Daspletosaurus tackled heavier horned dinosaurs.
Like Tyrannosaurus,Albertosaurus had small arms and a enormous head with recurved
serrated teeth. These teeth however, are more powerfully curved
than those of Tyrannosaurus. |

Unlike Tyrannosaurus, who underwent much evolutionary modify, all discovered specimens of Albertosaurus suggest that they didn't evolve much in over 10 million years, apart from for a trend towards a more slender or gracile form.
Albertosaurus is named after the Canadian province
of Alberta.
