A fossil unearthed in Australia by a volunteer digger has been identified as a rare, toothless dinosaur that roamed the country 110 million years ago.

The elaphrosaur, whose name means "light-footed lizard", was related to the Tyrannosaurus Rex and Velociraptor.

The five-centimetre (two-inch) vertebrae fossil was discovered during a dig near Cape Otway in Victoria in 2015.
