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 purport to represent.
The claim is the Tanis creatures were killed and entombed on the actual day a giant asteroid struck Earth.
