These cells found inside the T. Rex fossil were still flexible, meaning they were not fully fossilized. The red blood cells allow scientists to learn a lot about how the blood of a T. Rex flowed throughout its body. Also, polymerase chain reaction, a process of turning a fragment of a fossil into dust, allows scientists to gather chains of DNA from the dinosaur. This is all very strange, because it makes movies like Jurassic Park seem very possible, with preserved dinosaur DNA and recent advances in cloning.
