For example, if they believed it would take 200 million years for an ammonite (somehow) to turn gradually.. The best examples are fossils of animals or plants that lived for a very short period. After 20 minutes half the sample, 4 million atoms, remains undecayed. But unlike radiocarbon dating, the older the sample, the more accurate the dating. Dating Sample, Key Fission Product. Carbon-14, Radiometric Dating and Index Fossils.. But the number of neutrons in the. Naturally-occurring. In 1907, Boltwood dated a sample of urnanite based on uranium/lead ratios.

Radiocarbon dating can be used on samples of bone, cloth, wood and plant fibers. Herbaria are often used for plant sample observations after more than 10.
