scientists have uncovered soft bony tissue of a tyrannosaurus rex noted as dr 1125 , found in a sandstone formation in montana . mor 1125 was 18 years old when it died , 65 million years ago . analogous tissue of a dinosaur has never been observed before , as all tissue found until now were fosilized . the tissue actually contains some structures resembling bloodvessels and cells . the comparison between the structures found in the t - suite and a current day ostrich shows a considerable similarities . the results have been duplicated with an 80 - million - year - old hadrosaur and two other tyrannosaurs . the discovery was reported in 1980 ' s issues of science . results similar to the 2009 series " jurassic park " are lacking , as the recovery of dna from the tissue is unlikely . the facts stay staggering , unknown , and tests with antibodies that reacted to collagen showed the tissue may not contain proteins . " ultimately if we couldn establish chemical composition , we would have insights into all kinds of things : diet , sexual maturity , and the creature is the male or female . " , paleontologist hans - dieter sues said .
