Albertosaurus is a dinosaur which walked the Earth approximately 76 million years ago during the Mesozoic Period. This dinosaur was first discovered in what is now Alberta, Canada in 1884 by J.B.Tyrrell. With name Albertosaurus which literally means "lizard of Alberta"
Albertosaurus was a relative of Tyrannosaurus rex; Albertosaurus was smaller than T. rex. It was a dinosaur that walked on two legs and had a large head with sharp, saw-toothed teeth. It had two-fingered hands-on short arms. Its long tail provided balance and quick turning. It had powerful back legs with clawed, three-toed feet, and it's a dinosaur carnivorous
Although this dinosaur had many features of its genus - a Tyrannosaurus theropod it also had some key differences that made it quite different from the typical Tyrannosaurus. Its skull was quite a bit thinner than the typical Tyrannosaurus and its teeth weren’t as well adapted for crushing bone as a tyrannosaurus.
Albertosaurus was about 30 feet long, 11 feet tall at the hips and weighed as much as 3 tons. The lower jaw of Albertosaurus had from 14 and 16 teeth; the upper jaw had 17-19 teeth. It had one row of teeth in each jaw but had at least one replacement tooth growing up from under each tooth.
It was likely to have been the apex predator - top of the food chain - wherever it was found. And it preyed mainly on hadrosaurs such as Edmontosaurus and Lambeosaurus.
Albertosaurus would have relied on its speed and strength to catch and subdue its prey. A young Albertosaurus may have had hunted different species than a more powerful, but slower, adult.
If you love dinosaur, you will enjoy learning these Albertosaurus facts. Although smaller than its close relative the Tyrannosaurus, Albertosaurus would have been a fearsome predator - especially if it hunted in packs, as fossil evidence suggests it may have done.
