Finding red blood cells in 70 million year old bones. Still find that incomprehensible. Not sure King George didn't kill a dinosaur.
Red blood cells, and collagen from dinosaur bones. With the idea that even current museum hosted bones might have more??? Today is a wild day for me.
This is very heavily disputed and very much not consensus opinion. (see https://en.wikipedia.org/wiki/Homo_naledi#Possible_burials and https://www.sciencedirect.com/science/article/abs/pii/S00472...)
