After 50,000 years, a fossil won’t have any radiocarbon left in it.

Carbon-14 will have all disappeared by radioactive decay.

Recently living materials (the biobased component) have Carbon-14 in them while fossil materials (derived from petroleum) no longer have this weakly radioactive carbon isotope.

Thus all the carbon-14 in the product comes from the biobased component.

When they stop living, they stop taking in carbon-14 from the air around them, and the amount of carbon-14 in the remains gradually disappears.

A radiocarbon dating laboratory is able to measure the amount of carbon-14 remaining in a fossil.

Headquartered in Miami, Florida, Beta Analytic provides biobased content / renewable carbon measurements to top commercial organizations, government agencies, scientists and engineers.

Therefore all living plants, animals, and human beings have the same amount of carbon-14 in their bodies at the same time.When a plant stops assimilating carbon dioxide or when an animal or human being stops eating, the ingestion of carbon-14 also stops and the equilibrium is disrupted.From that time forward, the only process at work in the body is radioactive decay.Radiocarbon immediately reacts with oxygen in the air to form carbon dioxide (CO2).

This carbon dioxide rapidly mixes throughout the atmosphere, where at ground level it is taken in by plants during photosynthesis.This half-life is about 5,700 years and means that every 5,700 years the amount of carbon-14 in a fossil is only one-half of what it was 5,700 years ago.
