Describe how rock fossils are formed.

What are two different ways that geologists can use to age fossils?

Solution

1). Permineralization or petrification is the most typical form of fossil formation. The soft tissues of the organism decays within the sediment, leaving behind the hard structures such as skeleton. Skeleton contains minerals, when water seeps into the skeleton, the minerals are dissolved in the water and form crystals within the spaces of remains. This crystallization process turns the skeleton remains into hard structures while encasing the sedimentary rock.
