And how was Albertosaurus? Well, this animal had many curious things. For example, Albertosaurus was a fearsome hunter, its bite while being less potent than the T.Rex, was very powerful, as well as the largest of the crocodiles, which are animals with bite even more powerful live.
We could say it was like a smaller version of Tyrannosaurus, but not that much less effective as a predator. Because when weighing 2 tons (nearly half of T. Rex), Albertosaurus could be quicker, faster and agile. An estimated could exceed 50 km / h (31 mi/h)... To get an idea, Usain Bolt (the fastest man in the world) reaches 37 km / h (22 mi/h).
The dimensions of this predator prehistoric were:
Weight: up to 2 tons (4400 lb).
Length: 10 meters (33 ft).
Skull: 1.2 meters (4 ft).
Height: 3.5 meters (10 ft).
As you see, it was so small, was a smaller version of T.Rex, and in fact, the only impediment to not become the apex predator of the late Cretaceous in North America, was this, that the T.Rex occupied that position.
Other characteristics of Albertosaurus was that had small arms, hardly useless.
Also had bony protrusions on the eyes which had the role of protecting the eye when producing its deadly bite.
And finally, have sharp teeth on the inside a form lumber, this allowed it to tear the flesh once bitten and pulled with his strong neck.
Albertosaurus really is the name of a genus and now consists of three species, but the most representative was Arctunguis Albertosaurus.
