The remains of Britain's oldest known Jurassic dinosaur have been unearthed in Wales. Scientists named the new species Dracoraptor hanigani, literally "dragon robber."
The 200-year-old bones were first found in 2014, discovered beneath a cliff on a beach in Wales by a pair of fossil-hunting brothers, Rob and Nick Hanigan. The Hanigans relayed their discovery to paleontologists in England.
A year later, a paleontology student from the University of Portsmouth found foot bones at the same site. Excavations began in earnest, with paleontologists from Portsmouth, the University of Manchester and the National Museum of Wales leading the way. Skull, claws, teeth and foot bones were successfully removed from the site.
