Newly discovered fossils show the existence of a hammer head dinosaur, thought to have lived around 244 million years ago.

The Atopodentatus unicus was a herbivore with a skull the shape of a "vacuum attachment".

Dr Nick Fraser, from the National Museum of Scotland, worked on the discovery and said "the bizarre animal is the size of a crocodile, with a very tiny head".

Fraser said the Atopodentatus unicius translates into "unique bizarre dentition".
