Omphalosaurus
Omphalosaurus was a marine reptile that lived in the Triassic Period, not a dinosaur. It had strange button-shaped teeth that it used to crush hard-shelled animals like ammonites. This reptile was a slow swimmer that probably sucked in its food and then ground it up.1

Utuntu dushimishije
Omphalosaurus means 'button lizard' because its teeth look like small buttons.1
Its teeth were arranged in a pavement-like pattern, not in neat rows like most other ichthyosaurs.2
The enamel on its teeth had a texture like an orange peel, which helped it grip and crush shells.1
Omphalosaurus had hollow ribs, which is unusual for an ichthyosaur and may have helped it float or stay buoyant.2
It lived during the Early to Middle Triassic, about 248 to 237 million years ago.3
Fossils of Omphalosaurus have been found in Nevada, Germany, Poland, and Svalbard.3
