In the early years of the Jurassic Period, when the world was recovering from one of the worst mass extinctions on record, a modest meat-eating dinosaur from Wales helped pave the way for some of the most fearsome predators ever to stalk the Earth.

Scientists on Wednesday announced the discovery of fossil remains of a two-legged dinosaur called Dracoraptor that lived 200 million years ago and was a forerunner of much later colossal carnivores like Tyrannosaurus rex, Allosaurus and Spinosaurus.

Dracoraptor means "dragon thief." The Welsh flag bears a red dragon.
