was working with a T. rex skeleton harvested from Hell Creek, she noticed that the fossil exuded a distinctly organic odor. "It smelled just like one of the cadavers [dead bodies] we had in the lab who had been treated with chemotherapy before he died," she says. Given the conventional wisdom that such fossils were made up entirely of minerals, Schweitzer was anxious when mentioning this to Horner. "But he said, 'Oh, yeah, all Hell Creek bones smell,'" she says. To most old-line paleontologists, the smell of death didn't even register. - Discover Magazine
I am not sure what point you are trying to make with the dinosaur DNA. Somebody claims some Dino bones somewhere had an odor? So what? What proof is there the odor was decay? We're they tested? Do you have a lab report showing tissue with DNA were found in a stalagtite cave believed to be 100,000 years old? Really it sounds like some kind of modern urban legend, "The Fossils That Had an Odor!"
