Carbondated dinosaur bones are less than 40, years old. Researchers have found a reason for the puzzling survival of soft tissue and collagen in dinosaur bones — the bones are younger than anyone ever guessed. Carbon C dating of multiple samples of bone from 8 dinosaurs found in Texas, Alaska, Colorado, and Montana revealed that they are only 22, to 39, years old. Since dinosaurs are thought to be over 65 million years old, the news is stunning — and more than some can tolerate.

The Saurischan Dinosaurs". Carbonates are only one of many potential sources of exogenous carbon, and other sources are not as easily removed by treatment with acetic acid. Are a few of the pros and cons of keeping certain dinosaurs as your house pets:.
According to the researchers, some of the dinosaur bones in the samples appeared to be thousands of years old. This unusual reading seems to contradict the notion that all of the dinosaurs that once roamed the Earth became extinct tens of millions of years ago. According to the researchers, the soft tissue that they analyzed appeared to have been decomposing and eroding for thousands of years rather than millions. Naturally, these results seemed completely baffling to the researchers who presumed that the dinosaurs in question, including a Tyrannosaurus Rex and a Triceratops, have been extinct for many millions of years.
