A small cousin of the famous Tyrannosaurs Rex, the Albertosaurus was one formidable dinosaur genus that most likely lived before the T. Rex. It was smaller than T. Rex and yet a terrifying dinosaur that possibly hunted in packs, taking advantage of their speed. It was, in all its rights, the apex predator of its local ecosystem. In this article on Albertosaurus facts, we are going to learn a few things about the animal’s life.
Before we start with the facts…

Interesting Albertosaurus Facts: 1-5 | Where, When, Discovery
1. Albertosaurus lived during the Late Cretaceous Period some 73 to 70 million years ago.
2. The region where this dinosaur lived was western North America. However, its range was very restricted.
3. The fossils of the dinosaur were found in Alberta province of modern-day Canada. The Alberta province is vast and narrow stretch of barren area that sits atop the Montana state.
4. Albertosaurus was first discovered by Joseph Tyrrell in 1884. By profession, Tyrell was a map-maker and a geologist.
5. Tyrrell was surveying the Red Deer River area when in found the incomplete skull of the dinosaur.

6. Another partial skull was unearthed from near the same region where the previous discovery was made. However, this discovery came in 1889.
7. Then entered Barnum Brown in 1910. He was a paleontologist from America and was responsible for discovering T. Rex back in 1900. In 1910, he found the remains of a large group of Albertosaurus. However, he uncovered remains from only 9 different individuals.
8. In 1997, a group of paleontologists from Royal Tyrrell Museum of Paleontology (the museum has been named after Joseph Tyrrell) went to the same place where Barnum Brown visited and discovered specimens of 13 more Albertosaurus.
9. That was not the end. Many more Albertosaurus specimen have been discovered from the same region where the first set of fossils were uncovered.
10. It was Henry Fairfield Osborn who named the dinosaur as Albertosaurus in year 1905.
Interesting Albertosaurus Facts: 11-15 | Naming, Physical Appearance
11. The name Albertosaurus has two parts – Alberto and saurus. The first part is derived from the Alberta region where the fossils were found.
12. The second part ‘saurus’ is actually a Greek word which means ‘lizard’. The species “A. sarcophagus” actually means ‘flesh-eating lizard from Alberta’.
13. In case you are having difficulty with pronunciation, here is how you pronounce it: ‘al-ber-tuh-sawr-us’. That’s easy.
14. When it comes to physical appearance, the Albertosaurus looked very much like the T. Rex but only, it was petite compared to the ferocious T. Rex. Albertosaurus was nearly half the size of T. Rex.
15. A fully grown adult Albertosaurus used to be nearly 30 feet long and at the hips, it was 11 feet tall, weighing as much as 2 tons.

16. Albertosaurus was a tyrranosaurid. This means that it was a bipedal predator. Just like T. Rex, this dinosaur also had two tiny forearms each having two fingers.
17. The head was quite massive compared to the body and it boasted 15 razor-sharp teeth on upper jaw and 20 teeth in lower jaw.
18. A closer study of the skulls have led many scientists to believe that Albertosaurus didn’t really have the ability of crushing bones as T. Rex. It however had a bit similar to that of Kimono Dragon.
19. Scientists also believe that the bite of the Albertosaurus was capable of inflicting a septic wound to the victim.
20. The heavy head of the Albertosaurus was balanced out by the long tail.

21. The Albertosaurus belongs to the Tyrannosauridae family. The Tyrannosaurus Rex is also the member of the same family.
22. Unlike the forward-facing eyes of Tyrannosaurus Rex, the eyes of the Albertosaurus were located on the sides of the heads.
23. Since the fossils of the dinosaur were found in groups, scientists believe that the dinosaur lived and hunted in packs.
24. The dinosaur was capable to reaching walking speed of 8 to 13 miles per hour (14 to 21 kilometers per hour) and was capable of attaining a running speed of 19 miles per hour or 31 kilometers per hour.
25. Scientists say that Albertosaurus would often engage in furious fights with members of its own family and often bite on the facial area.

26. According to William Abler – an expert on dinosaur teeth – a serrations line on the teeth of Albertosaurus helped in keeping the teeth from cracking when the dinosaur ate.
27. The ancestors of the Albertosaurus actually originated in Asia near modern-day China some 199.6 to 145.5 million years ago during the Jurassic Period. Those ancestors were not even close to being intimidating and would barely grow 6 feet long as fully-grown adults. One such ancestor was Dilong paradoxus.
28. A detailed study of the fossils of the Albertosaurus has revealed that the dinosaur experienced the maximum growth when they were into their teens and added nearly 250 pounds per year. By the time they reached 20 years old, they would have attained their maximum size of 30 feet. After that, it would live for just another 10 years.
29. Scientists think that the Gorgosaurus that was named some 100 years before the discovery of Albertosaurus is possibly the same dinosaur as Albertosaurus.
30. Scientists believe that the Albertosaurus had brightly colored small crests or horns above its eyes and used them for attracting mates.
