Carbon dating chicken bone

Radiocarbon dating reveals that the bones are not prehistoric, but are still the earliest chicken remains known from New Zealand.Two of the bones pre-date permanent European settlement ( 1803s onwards) but overlap with the arrival of James Cook's second voyage (1773–1774), and, therefore, they are likely to be chickens, or progeny thereof, liberated during that voyage.When calcium acetate is formed, it diffuses out of the bones and into the water component of the vinegar.

The organic material, on the other hand, can make the date too young (due to younger contaminants physically present in the shell).Two part answer: original article and refutation The chicken bones were discovered at an archaeological site called El Arenal, on the south coast of Chile, alongside other materials belonging to the indigenous population.Tests on the bones indicate the birds arrived well before any European arrival.Many of these discoveries, however, have been contentious within the paleontological community, and the presence of molecular-level preservation in the fossil record remains controversial.This is because proteins and other molecular components are thought to break down within about four million years.
