Bony armour across the back and a rounded club at the tail tip.

The bony plates on Ankylosaurus look like a sturdy coat of armour. Follow its back towards the tail, all the way to the rounded club at the very end.

Learning from fossils

No complete Ankylosaurus skeleton has been found, so the exact arrangement of its back armour is still being studied.

About this museum

A little museum made by a developer dad for his daughter

I’m Leon, a developer and a dad. When my daughter was three, dinosaur chases on television frightened her, so I made a 3D prehistoric animal museum where she could look quietly and listen only when she wanted to.

The museum is free, with no sign-up, adverts or visitor tracking. Finding one interesting detail at a time is plenty.
