UNFOSSILIZED SOFT TISSUE HAS BEEN FOUND IN DINOSAUR FOSSILS
_______________
“It smelled just like one of the cadavers we had in the lab who had been treated with chemotherapy before he died.”
That was the description that Mary Schweitzer gave to describe the odor that was coming from a Tyrannosaurus Rex skeleton that was excavated from the Hell Creek Formation in Montana. Schweitzer was working as a researcher at the Museum of the Rockies in Bozeman, Montana and was examining the medullary bone of that skeleton when an assistant put a fragment of the bone in dilute acid to clean deposits off. What they found in the decalcified bone was soft stretchy material something not expected in solid mineral deposits. This led them to decalcify other bone samples, what they ended up finding was a soft stretchy fibrous matrix that was inside of the bone when the T.rex was alive. [1]
