T. Rex Analysis Supports Dino-bird Link

For the first time, researchers have read what they say is the biological signature of a tyrannosaur — a signature that confirms the increasingly accepted view that modern birds are the descendants of dinosaurs.

 

The signature doesn't come from studying the shape of the 68 million-year-old dinosaur's fossilized bones, but from analyzing the organic material found inside those bones. It's not DNA — despite what you've seen in movies like "Jurassic Park," that genetic material couldn't be recovered. But researchers say it's the next-best thing: collagen proteins that were isolated using techniques on the very edge of what's possible today.

Rest of story here.
