This is Lystrosaurus, a plant-eating synapsid from the Late Permian and Early Triassic, not a dinosaur. Look at its short face, beak-like mouth and two tusks; this funny little animal is hard to forget!
Fossils of Lystrosaurus date to the Late Permian to Early Triassic (about 255–247 million years ago) and have been found in Southern Africa, Antarctica, India, Asia.

Leon Made This
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.
