You.. have to try harder
No wonder they went extinct. Blond dinos – Joke!
Fossil beds that preserve soft tissues like hair and feathers are called lagerstatte – and while fossilized hair is about 5 times more rare than feathers it does happen. (It’s rarer possibly because it’s easier for a paleontologist to spot a single feather than a single hair)
Fossilized mammal and pterosaur hair from 125 million years ago has been found.
