Permineralization is a process of fossilization that occurs when an organism is buried.

The empty spaces within an organism (spaces filled with liquid or gas during life) become filled with mineral-rich groundwater.

Fossils are the preserved remains or traces of animals, plants, and other organisms from the past.

Fossils range in age from 10,000 to 3.48 billion years old.

Small-scale permineralization can produce very detailed fossils.

For permineralization to occur, the organism must be covered by sediment soon after death, or soon after the initial decay process.

As radioactive isotopes of elements decay, they lose their radioactivity and become a brand new element known as a daughter isotope.

By measuring the ratio of the amount of the original radioactive element to the daughter isotope, scientists can determine how many half-lives the element has undergone and from there can figure out the absolute age of the sample.
