Scientists find fossil of dinosaur 'killed on day of asteroid strike'





https://www.theguardian.com/science/2022/apr/07/fossil-dinosaur-killed-asteroid-strike-thescelosaurus-north-dakota-extinction

Scientists believe they have been given an extraordinary view of the last day of the dinosaurs after they discovered the fossil of an animal they believe died that day.

The perfectly preserved leg, which even includes remnants of the animal’s skin, can be accurately dated to the time the asteroid that brought about the dinosaurs’ extinction struck Earth 66m years ago, experts say, because of the presence of debris from the impact, which rained down only in its immediate aftermath.

“It’s absolutely bonkers,” said Phillip Manning, a professor of natural history at the University of Manchester. He told BBC Radio 4’s Today programme the thescelosaurus leg discovered at the Tanis dig site in North Dakota was the “ultimate dinosaur drumstick”.

He said: “The time resolution we can achieve at this site is beyond our wildest dreams … This really should not exist and it’s absolutely gobsmackingly beautiful. I never dreamt in all my career that I would get to look at something a) so time-constrained; and b) so beautiful, and also tells such a wonderful story.”

4. The bottom photo is magnificent

I imagine that the animal was killed instantly from the flash and heat, but the body was not turned to ashes. Then it was covered in falling debris and a goodly amount of iridium.

That is a heck of a find!

7. I have a vial of glass beads from the boundary layer.

When I look at it, I wonder how much is fried dinosaur DNA.

9. Probably quite a lot

Microscopic glass beads containing human DNA from Hiroshima and Nagasaki have been found in the oceans. Pretty mind-blowing concept.
