|— Allen, about Albertosaurus|
Albertosaurus ("Alberta Lizard" or "Lizard from Alberta") was a theropod dinosaur that lived in North America during the Late Cretaceous period and was also a dinosaur of relation to Tyrannosaurus Rex. Albertosaurus has been informally referred to even by Palaeontologists as the, "sports car edition of T. rex", because it is indeed more slender, with a narrow skull.
Albertosaurus lived in Western North America during the Late Cretaceous period from 78–65 million years ago, living up until the end of the Cretaceous period when it died out with the other dinosaurs. It shared its environment with Parasaurolophus, Nyctosaurus, Troodon, and its competitor Deinosuchus. Hence it's name, it was first discovered in the state Alberta, Canada.
Although small compared to other, larger predatory dinosaurs, such as Allosaurus, Giganotosaurus, and even their cousins Tarbosaurus and even Tyrannosaurus Rex, Albertosaurus was still one of the largest carnivorous dinosaurs that ever walked planet Earth. They measured 30 feet long from head to tail, stood 11 feet tall at the hips, and weighed as much as 3 tons. They were smaller, faster, and more light weight than T. rex.
Albertosaurus could also run at speeds as fast as 30–38 mph, just about as fast as a modern African lioness.
Being a member of the Tyrannosaur family and like many large predatory dinosaurs, Albertosaurus was a pack hunting predatory dinosaur, hunting in pairs, packs of three, and sometimes numbers of five and even living in numbers of several individuals, including juveniles. They were true hunters and worked together to bring down their prey.
In my JournalsEdit
With their names meaning "The Lizard from Alberta", Albertosaurus is a relative of Tyrannosaurus itself, but only they were smaller and more light weight. Because of their lightweight, it allowed them to run faster than Tyrannosaurus, running nearly as fast as a modern African lioness.
Measuring 30 feet long, standing over 10 feet tall, and weighing 3 tons, Albertosaurus were the top predators of their time, only rivaled by the giant crocodile and their competitor Deinosuchus. In addition, these predatory dinosaurs also hunted in packs.
