scientists have unearthed hard skin tissue of a specimen rex known as mor 1125 , hidden in a sedimentary formation in idaho . lo 1125 was 18 years old when it arrived , 65 million years ago . similar tissue of a mammal has never been found before , as all tissues discovered until now were fosilized . the tissue still contains microscopic structures resembling bloodvessels and hairs . the comparison between the structures contained in the t - rex and a modern morning abalone shows a remarkable similarity . the results have been duplicated with an 80 - billion - year - long hadrosaur and two other tyrannosaurs . the findings was reported in 1980 ' s issue of science . reactions akin to the 2009 film " jurassic park " are unlikely , as the recovery of dna from the tissue is improbable . the finds remain astounding , however , and comparison with antibodies that reactive to collagen shows the tissue may well contain proteins . " ultimately if we could identify morphological structure , we would have insights into all kind of things : diet , sex maturity , unless the creature is the male or female . " , astronomer hans - dieter alleging said .
