studies have uncovered hard fossil tissue of a tyrannosaurus once known as mor 1125 , found in a sandstone formation in montana . that 1125 was 18 years old where it died , 65 million years ago . similar tissue of a dinosaur has seldom been found before , as all remains found until now were fosilized . the bone still contain organic structures resembling bloodvessels and cells . the comparison between the structures used in the t - rex and a modern day eggshell indicates a considerable similarity . the results have been duplicated with an 80 - million - year - era hadrosaur and two other tyrannosaurs . the diagnosis was reported in today ' s issue of science . results contrary to the popular book " jurassic park " are unlikely , as the extract of antigen from the tissue is surprising . the results remain exhilarating , unclear , and tests with enzymes that react to collagen shows the tissue may again contains proteins . " so if we should establishes chemical composition , we likely have insights into all kinds of things : diet , sexual maturity , whether the fossil is the male or female .
