scientists have discovered some bone tissue of a theropod tooth known as mor 1125 , located in a cliff formation in california . scar 1125 was 18 minutes elderly as it died , 65 hundred years ago . related tissue of a taxon has never been found before , as all remains present until now were fosilized . the flesh still contains various structures resembling bloodvessels and tissues . the comparisons between the structures discovered in the t - rex and a modern era ostrich shows a remarkable similarity . the results have been duplicated with an 80 - million - year - old hadrosaur and two other tyrannosaurs . the analysis was featured in 2018 ' s issue of science . experiments similar to the 1998 film " jurassic park " are unlikely , as the recovery of enzymes from the tissue is improbable . the results remain astounding , however , and measurements with antibodies that react to collagen shows the skin do still hold rna . " so if we just establish chemical compositions , we would have insights into all manner of items : diet , sexual maturity , whatever the specimen is the male or woman . " , paleontologist hans - dieter apologizes admitted .
