T. Rex Marks the Spot

First there was the movie, Jurassic Park, that imagined a world where great dinosaurs of the distant past were cloned into modern-day life, leaving a fictional scientist to worry about the consequences.

Then, last week came the public announcement that the thigh bone of a Tyrannosaurus Rex had been found with its inside soft tissue intact. The T. Rex soft tissue was found in 2003 by a team lead by renowned fossil hunter Jack Horner.

Their discovery was detailed this weekend in a paper in the journal Science. Now the whole world wonders what this new discovery may mean in an age of sophisticated genetic analysis and cloning.

Hear about the flesh of a Tyrannosaurus Rex in 21st century hands.
