Protein links T. rex to chickens

from the bbc:

Protein extracted from 68 million-year-old T. rex bones has shed new light on the evolutionary link between dinosaurs and birds.

Researchers compared organic molecules preserved in the T. rex fossils with those of living animals, and found they were similar to chicken protein.

as you can see, some evolutionary resemblances are much more immediately obvious than others.
