Peering through a microscope at a slice of dinosaur bone, she spotted what looked for all the world like red blood cells. It seemed utterly impossible—organic remains were not supposed to survive the fossilization process—but test after test indicated that the spherical structures were indeed red blood cells from a million-year-old Tyrannosaurus rex. In the years that followed, she and her colleagues discovered other apparent soft tissues, including what seem to be blood vessels and feather fibers. But controversy accompanied their claims. Skeptics argued that the alleged organic tissues were instead biofilm—slime formed by microbes that invaded the fossilized bone.

Imagine you are hunting fossils, and you find a fossil skull, some rib bones, and thigh bones. As you chip away the dirt and rock from the skull, to your amazement, you find that it has a well-defined bump on the top of it as well as cone-shaped spikes and knobs surrounding it, almost in the shape of a crown. What dinosaur could this be? You check the rest of the fossil, and nothing really out of the ordinary stands out. After examining the skull closer, you find that the bump most likely is made of bone, several inches thick! So, what was the dinosaur with the bump on its head?
ERRORS ARE FEARED IN CARBON DATING
Neatly dressed in blue Capri pants and a sleeveless top, long hair flowing over her bare shoulders, Mary Schweitzer sits at a microscope in a dim lab, her face lit only by a glowing computer screen showing a network of thin, branching vessels. From a dinosaur. It was big news indeed last year when Schweitzer announced she had discovered blood vessels and structures that looked like whole cells inside that T. The finding amazed colleagues, who had never imagined that even a trace of still-soft dinosaur tissue could survive.
This is how carbon dating works: Carbon is a naturally abundant element found in the atmosphere, in the earth, in the oceans, and in every living creature. C is by far the most common isotope, while only about one in a trillion carbon atoms is C C is produced in the upper atmosphere when nitrogen N is altered through the effects of cosmic radiation bombardment a proton is displaced by a neutron effectively changing the nitrogen atom into a carbon isotope. The new isotope is called "radiocarbon" because it is radioactive, though it is not dangerous. It is naturally unstable and so it will spontaneously decay back into N after a period of time.
