A 1990 experiment that involved radiocarbon dating of pieces from two dinosaur bones—that test will not be covered, for it involved a controversy regarding a report of shellac that may have contaminated one of the two sample sources.
The stable form of carbon is carbon 12 and the radioactive isotope carbon 14 decays over time into nitrogen 14 and other particles.
This one is dedicated to Susan Gerbic and her team of wikipedia editors, fighting the good fight against facts claimed without references. You mean that somebody just made up all that stuff about them? Since last January we’ve been bringing science programming to bars, theaters, and comic cons in Colorado.
As I often say during Facebook arguments: link, or it didn’t happen. Our flagship program is called the Peer Revue, where we teach scientists to perform stand-up comedy then throw them on stage in front of a live audience.
We generally refer to those numbers as “carbon-14 dates.” Consider now how the C dating method has been used on dinosaur remains.
(I would be delighted beyond words if scientists had already begun dating pterosaur fossils through radiocarbon methods, but it appears we need to wait for that.) Shellac contamination?
