Ankylosaurus fossils have been found in the of Montana and Wyoming in the USA. They have also been found in the Canadian province, Alberta.
Ankylosaurus was covered in bony plates of armor on its back, head, neck, tail, and sides. The plates were there two make Ankylosaurus impenetrable to attack by predators. They were very effective, too. Unlike fossils of Edmontosaurus and Triceratops, two herbivorous dinosaurs that lived in the same place at the same time as Ankylosaurus, Ankylosaurus fossils are never found with Tyrannosaurus tooth marks.
Ankylosaurus fossils have been found in the Hell Creek Formation of Montana, the Lance Formation of Wyoming, and the Scollard Formation of Alberta, Canada. Where they are most common specifically I don't know.
In Alberta, Ankylosaurus fossils have been found in the Scollard Formation. The Scollard Formation is located about halfway between the cities of Edmonton and Calgary. The Scollard Formation also holds fossils of other dinosaurs, such as T-rex, Triceratops, and Pachycephalosaurus.
Ankylosaurus fossils have been found in Wyoming and Montana in the USA, and Alberta, Canada. Between 66.5 and 65.5 million years ago, this area was a coastal floodplain.
Ankylosaurus's entire back, tail, neck, and head was covered in bony armor that was impenetrable by Tyrannosaurus. In addition, Ankylosaurus was armed with a bony tail club that would easily have been lethal to an attacking Tyrannosaurus. For these reasons, it is no surprise that Ankylosaurus fossils are never found with Tyrannosaurus bite marks, unlike the fossils of other contemporary herbivores like Edmontosaurus and Triceratops, which are frequently found to have been eaten by Tyrannosaurus. Thus, it is safe to say that Tyrannosaurus rarely, if ever, attacked Ankylosaurus.
Ankylosaurus fossils have been found in the Hell Creek Formation of Montana and the Lance Formation of Wyoming. They have also been found in the Scollard Formation of Alberta, in Canada.
Ankylosaurus was native to western North America. Its fossils have been found in Montana, USA, and Alberta, Canada, and date to between 66.5 and 65.5 million years ago.
Ankylosaurus fossils have been found in North America, specifically, Montana (USA) and Alberta (Canada).
Ankylosaurus fossils have been found in Alberta, Canada, and Montana, USA. They date to between 66.5 and 65.5 million years ago, right at the end of the Mesozoic era, or the "Age of Reptiles."
The scientific name of an ankylosaurus is Ankylosaurus magniventris.
Ankylosaurus only existed for about a million years, from 66.5 to 65.5 million years ago. Its existence was cut short by the K-T Extinction Event, which eliminated all non-avian dinosaurs. It is too difficult to know how long Ankylosaurus would have lasted if it weren't for the K-T Extinction. However, Ankylosaurus was the most successful dinosaur in its time and place when it comes to avoiding predation. Ankylosaurus fossils are never found with bite marks, unlike the bones of other herbivorous dinosaurs like Edmontosaurus and Triceratops.
