Meet today’s friendCeratopsid dinosaur

Regaliceratops

A large nose horn, small brow horns and a crown-like frill.

The frill behind Regaliceratops’s head has bony points around the edge, like a crown. Look at the horn on its nose, then the little horns above its eyes.

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.
