All non-avian dinosaurs died out 65.5 million years ago during the K-T extinction event. Ankylosaurus was among the last dinosaurs on Earth, and was wiped out by the K-T extinction event.
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 remains date to between 66.5 and 65.5 million years ago. This was during the Maastrichtian stage of the Cretaceous period of the Mesozoic era.
Iguanodon lived between 126 and 125 million years ago in Europe. Deinonychus lived between 115 and 108 million years ago in North America. Oviraptor lived about 75 million years ago in Asia. Triceratops lived between 68 and 65.5 million years ago in North America. Tyrannosaurus lived between 67 and 65.5 million years ago in North America. Ankylosaurus lived between 66.5 and 65.5 million years ago in North America.
Ankylosaurus didn't live in the desert. They lived on the coastal plains of western North America between 66.5 and 65.5 million years ago. The environment was warm, humid, and subtropical, with wet and dry seasons. However, some other ankylosaurs, which were relatives of Ankylosaurus, did live in the Gobi Desert of Asia. Why they lived there is difficult to say. It's similar to asking why camels live in the desert.
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 lived in what is now Montana, Wyoming, and Alberta 66.5 to 65.5 million years ago. Back then the area was a humid, subtropical floodplain with distinct wet and dry seasons.
Ankylosaurus lived between 66.5 and 65.5 million years ago, at the end of the Maastrichtian stage, the last stage of the Cretaceous period. The Cretaceous period was the third and final period of the Mesozoic era.
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."
From about 180 million years ago until about 65 million years ago.
Ankylosaurus lived between 66.5 and 65.5 million years ago. That was during the end of the Maastrichtian stage, the last stage of the Cretaceous period, which was the last period of the Mesozoic era.
Euoplocephalus was a close cousin of Ankylosaurus. However, Euoplocephalus was smaller that Ankylosaurus. Ankylosaurus weighed about 4 tons and was almost 30 ft. long. Euoplocephalus was over 2.5 tons and about 20 ft. long. They also lived at different times and in different areas, with Euoplocephalus living in western Canada around 72 million years ago and Ankylosaurus living in the central US about 65 million years ago.
They lived from 2.0 million years ago to 1.2 million years ago.
