Albertosaurus was a Tyrannosaur, a smaller relative of T. rex. It lived earlier and was the top predator on land in North America 75-70 million years ago. Unlike it's more powerful relatives, Albertosaurus was faster and more agile like Gorgosaurus. It had a narrower skull and longer arms than Tyrannosaurus. It was first found in Alberta in 1905, giving it it's name. Even though Albertosaurus was built for speed and hunted duckbills, it was powerful enough to hunt and eat horned dinosaurs such as Pachyrhinosaurus.
