Description
Famed for its clubbed tail and the armor plates that cover its back, Ankylosaurus is a genus of Ankylosaurus that lived around 70m years ago during the Late Cretaceous period. Ankylosaurus’ protective osteoderms and robust build – the average specimen weighs 8 tons and is 9.6m in length - defend it from predators such as Tyrannosaurus rex, while its large stomach digested up to 60kg of ferns and shrubs every day.
Discovery
Ankylosaurus was discovered in the Hell Creek Formation, Montana by Barnum Brown, four years after the famous paleontologist, known as ‘Mr. Bones’, had discovered Tyrannosaur rex. The first fossils found were a collection of bones including two teeth and a skull fragment, although Brown actually unearthed numerous osteoderms in 1900, but incorrectly attributed them to Tyrannosaurus. Further Ankylosaurus fossils were found in Canada in 1910, including a complete skull.
Paleoecology
Ankylosaurus lived in Canada and the western United States, which had a warm, humid climate at that time, and preferred to stay close to rivers, forests and wetlands, allowing them to cool off during hotter periods.
