the dinosaurs here were found all around the world, and they span their entire 180 million year reign on the planet. it s widely accepted that this domination came to an end when the asteroid struck. but there s a mystery. no one s ever found direct evidence of a dinosaur killed by the impact, or even a fossil dinosaur that died within 1,000 years of it. now, though, a discovery at tanis may have changed that. there s something here. that s hard. that s bone right next to the skin. this is the moment a dinosaur s leg was discovered. it was captured by a bbc crew for a documentary called dinosaurs, the final day. the fossil part is remarkably well preserved. it belongs to a small plant eating dinosaur called a thescelosaur, and scientists think it died in a huge flash flood, set off by shock waves from the asteroid strike. this looks like an animal whose leg has simply been ripped off really quickly. there s no evidence

now a discovery may have changed that. there is something here, that is hard. that is bone right next to the skin. this is the moment dinosaur s leg was discovered, captured by a bbc documentary crew. the fossil belongs to a small plant eating dinosaur called a thescelosaur. the team thinks it died in a huge flash flood settled by shock waves from the asteroid strike. this looks like an animal whose leg has been ripped off really quickly. there is no evidence of disease, there are no obvious pathologies or traces of the leg being scavenged. this could be the first bit of dinosaur ever found that died as a direct result of being involved in the cataclysm that involved after the meteorite hit. tanis is 2000 miles away from where the asteroid struck but what links the two are these tiny beads scattered amongst the fossils. it is thought they are remnants of the molten rock thrown up by the impact which rained back down
