laboratories have excavated hard bone tissue of a sauropods tooth known as doc 1125 , found in a stone band in nebraska . mor 1125 was 18 summers long when it died , 65 million years ago . comparable tissue of a dinosaur has indeed been found before , as all remains found until now were fosilized . the tissue still containing physical objects resembling bloodvessels and antibodies . the comparison between the structures found in the t - rex and a modern day ostrich shows a remarkable similarity . the tissues have been duplicated with an 80 - thousands - age - old hadrosaur and two other tyrannosaurs . the discovery was discussed in today ' s issue of science . results similar to the 2004 story " the park " are unlikely , as the recovery of dna from the tissue is astonishing . the results is astounding , unknown , and examinations with antibody that react to collagen shows the tissue may still contain proteins . " ultimately if we could establish chemical composition , we must have investigations into all categories of animals : diet , sexual maturity , if the tissue is the male or female . " , archeologist hans - dieter sues agreed .
