Researchers unearthed part of a bone called a tarsometatarsus, which is found in the lower leg of birds.
After comparing it with other species, they discovered that it belonged to a small parrot, '' reported.
The woody internal structure was clearly evident, thus the samples were not the remains of roots that had grown into this weathered rock from trees on the present land surface.
When sampled, the fossil wood readily splintered, diagnostic of it still being ‘woody’ in spite of its impregnation with iron minerals during fossilisation.
Fossils can be dated by the number of mutations in their genes.Carbon-14 cannot be used to date biological artifacts of organisms that did not get their carbon dioxide from the air.This rules out carbon dating for most aquatic organisms, because they often obtain at least some of their carbon from dissolved carbonate rock.Levels of carbon-14 become difficult to measure and compare after about 50,000 years (between 8 and 9 half lives; where 1% of the original carbon-14 would remain undecayed).The question should be whether or not carbon-14 can be used to date any artifacts at all? There are a few categories of artifacts that can be dated using carbon-14; however, they cannot be more 50,000 years old.
