A stunningly preserved leg of a dinosaur found at the Tanis fossil site in North Dakota in the US is believed to be linked to the catastrophic asteroid event that wiped out the species 66 million years ago.
Scientists say that the leg which has skin still attached to it offers more insight into what happened when the dinosaur’s reign ended.
The BBC reports very few dinosaur remains have been found in rocks that record even the final few thousand years before they were wiped out, so these Tanis finds are something very special.
The BBC has spent the past three years filming at the Tanis site for a project with documentarian Sir David Attenborough.
