Ankylosaurus

Ankylosaurus was up to 8 metres (26 feet) long and weighed up to 8 tonnes (8.8 short tons), which is heavier than a male African elephant.134

Ankylosaurus was a plant-eater (herbivore). It ate low-growing plants like ferns, shrubs, and fruit, using its beak to snip them and small leaf-shaped teeth to chew.13

Yes, Ankylosaurus had a heavy club at the end of its tail made of fused bones. It could swing it powerfully from side to side to defend itself against predators like Tyrannosaurus rex.134

Probably only about 10 km/h (6 mph) at its fastest, a bit slower than a kid running fast. This is an estimate. Ankylosaurus was a slow, heavy, armoured dinosaur on four legs, but it could hurry a little when it needed to.13

No, Ankylosaurus was not bigger than T. rex. Ankylosaurus was up to 8 metres long, while Tyrannosaurus rex was much larger, reaching over 12 metres in length.13

No, Ankylosaurus did not have feathers. Its body was covered in bony plates called osteoderms, and it had a thick, scaly skin like other armoured dinosaurs.34

Ankylosaurus lived at the very end of the Age of Dinosaurs, about 68 to 66 million years ago, during the Late Cretaceous Period.134

Fossils of Ankylosaurus have been found in western North America, including Montana, Wyoming, South Dakota, Alberta, and Saskatchewan.134

Scientists are not sure if Ankylosaurus could swim. Its heavy body and short legs suggest it was not a good swimmer, but it may have been able to cross rivers if needed.3

The name Ankylosaurus means 'fused lizard' or 'bent lizard'. It refers to the fused bones in its skull and body that made it very strong.3
