Scientists in the US have announced the discovery of a new species of dinosaur. The fossils offer further clues to how the dinosaurs became extinct 66 million years ago.
Anzu wyliei is a strange bird-like creature that has a bony crest on top of a beaky head and a long tail like a lizard. It was identified from the partial remains of three skeletons collected in North and South Dakota.
The first detailed report about the Anzu wyliei is published today by the journal PLoS ONE.
Hans Sues, curator of vertebrate palaeontology in the department of palaeobiology at the Smithsonian's National Museum of Natural History in Washington, showed the BBC's Jane O'Brien what the skeleton looks like.
