Albertosaurus
Dinosaur (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
Dinosaur also tended to be less massive than T.
rex, as fine as its contemporary Daspletosaurus
(also a tyrannosaurid of similar length).
Albertosaurus was first discovered by Joseph B.Tyrrell in 1884 which is now displayed in the Royal Tyrrell Museum (now the marquee specimen of the museum). The
co-existence of these two animals have lead to the proposal
that they were specialized for killing different kinds of
prey: Albertosaurus Dinosaur may have went
after fleeter prey, like duck-billed dinosaurs
and ornithomimids, while Daspletosaurus tackled heavier
horned dinosaur.
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
Dinosaur.The massive head of
Albertosaurus was built for strength. It could withstand the shock as Albertosaurus crashed, open-mouthed, into its prey. Huge jaws carried the deadly sharp teeth, and spaces in the skull left room for bulging muscles.
Unlike Tyrannosaurus, who underwent much evolutionary modify,
all discovered specimens of Albertosaurus Dinosaur
suggest that they didn't evolve much in over 10 million
years, apart from for a trend towards a more slender or
gracile form.
The rear legs of Albertosaurus were powered by large muscles that pulled on the bones to make them move. The ankle and metatarsals worked as part of the leg, giving a longer stride.Albertosaurus Dinosaurs is named after the Canadian province
of Alberta.

Rich resources:
Albertosaurus Predator Author:Monique Keiran Publications:2002 Description:It talks about Albertosaurus. Some 75 million years ago,Albertosaurus, meat-eating predator Tyrannosaurus Rex died. But its death was beginning of its transformation into a fossil.
Concise Illustrated Dinosaurs Author:
Rupert Matthews Publications:1989 Description:Describes about many types of dinosaurs which roamed the earth in prehistoric times. It mainly focus on Albertosaurus which was lightly built for its size, so the creature was probably fairly agile.
