scholars have uncovered soft jaw tissue of a tyrannosaurus rex described as mor 1125 , found in a geologic formation in montana . mor 1125 was 18 years aged when it perished , 65 million years ago . similar dna of a taxon has rarely been recovered before , as all remains found until now were fosilized . the brain still contains microscopic structures resembling bloodvessels and cells . the comparison between the structures contained in the t - mount and a modern day ostrich shows a remarkable similarity . the results have been duplicated with an 80 - million - year - old hadrosaur and several other tyrannosaurs . the comparison was reported in today ' s issue of scientist . results contrary to the popular film " prospect park " are unlikely , as the recovery of dna from the tissue is improbable . the results be stupendous , however , and comparison with antibodies that react to fibers shows the tissue to again contain bacteria . " ultimately if we actually establish biological composition , we might have dug into all kinds of things : appetite , sexual immature , whether the specimen is the male or women .
