Wouldn't this require dinosaur DNA?
There were was a 1994 paper in Science where they thought they had
extracted DNA from 80 million year old bone fragments. Subsequent
work suggested they'd probably had fragments of human DNA which had
contaminated the bone fragments. Maybe there is something recent
I've missed?
Slightly off-topic, there are recent news stories about a Qld dinosaur
