Hold on to your butts: Researchers have found what appears to be remains of soft tissue inside fragments of 75-million-year old dinosaur fossils. While no one's cloning T-Rexes any time soon, this could be an exciting discovery in learning more about dinosaur physiology.
The tissue contains what looks to be red blood cells. If scientists can confirm that, it will inform whether they were warm blooded or cold blooded, which will then tell us much more about their size, behavior, and lifestyles.
The researchers are now looking into fossils of different ages and areas to see if they can find additional tissue inside the ancient bones.
