Carbon dating dino bones

This was a joint event of the American Geophysical Union (AGU) and the Asia Oceania Geosciences Society (AOGS).

It appears that the researchers approached the matter with considerable professionalism, including taking great pains to eliminate contamination with modern carbon as a source of the C signal in the bones.

Unwilling to challenge the data openly, they erased the report from public view without a word to the authors or even to the AOGS officers, until after an investigation.

The theoretical limit for C-14 dating is 100,000 years using AMS, but for practical purposes it is 45,000 to 55,000 years.That included protecting the samples, avoiding cracked areas in the bones, and meticulous pre-cleaning of the samples with chemicals to remove possible contaminants.Knowing that small concentrations of collagen can attract contamination, they compared precision Accelerator Mass Spectrometry (AMS) tests of collagen and bioapatite (hard carbonate bone mineral) with conventional counting methods of large bone fragments from the same dinosaurs.Visit Stack Exchange This site uses cookies to deliver our services and to show you relevant ads and job listings.By using our site, you acknowledge that you have read and understand our Cookie Policy, Privacy Policy, and our Terms of Service.
