Problem: Context: Scientists have uncovered soft bone tissue of a Tyrannosaurus Rex known as MOR 1125, found in a sandstone formation in Montana. MOR 1125 was 18 years old when it died, 65 million years ago. Similar tissue of a dinosaur has never been found before, as all remains found until now were fosilized. The tissue still contains microscopic structures resembling bloodvessels and cells. The comparison between the structures found in the T-rex and a modern day Ostrich shows a remarkable similarity. The results have been duplicated with an 80-million-year-old hadrosaur and two other tyrannosaurs. The discovery was reported in today's issue of Science. Results similar to the popular film "Jurassic park" are unlikely, as the recovery of DNA from the tissue is improbable. The results remain astounding, however, and tests with antibodies that react to collagen shows the tissue may still contain proteins. "Ultimately if we could establish chemical composition, we would have insights into all kinds of things: diet, sexual maturity, whether the specimen is the male or female.", paleontologist Hans-Dieter Sues said.
