From the BBC:
“Scientists have presented a stunningly preserved leg of a dinosaur. The limb, complete with skin, is just one of a series of remarkable finds emerging from the Tanis fossil site in the US State of North Dakota.
But it’s not just their exquisite condition that’s turning heads – it’s what these ancient specimens are purported to represent.
The claim is the Tanis creatures were killed and entombed on the actual day a giant asteroid struck Earth.
The day 66 million years ago when the reign of the dinosaurs ended and the rise of mammals began.
Very few dinosaur remains have been found in the rocks that record even the final few thousand years before the impact. To have a specimen from the cataclysm itself would be extraordinary.”Read the whole post and see the video here on BBC.com
