Are fossils formed

Answer 1

There are multiple methods of fossilization, but fossils generally are formed by rapid burial of organisms or traces of organisms by sediments.

Fossils occur when the organic material is filled with minerals or the cells of an organism is replaced by the minerals in water. Most of the minerals came from rocks and sands.

Here are the conditions for fossilization or permineralization:

1. Mineral-rich water like flood water or ground-erupted water.

2. Lack of oxygen - to prevent decomposition by oxygen.

3. Pressure - particularly in woods so that minerals can seep deep inside.

4. Usually occur within a few years - fossilization must occur quickly before decomposition takes place.

When a Plant or animal dies in a watery environment and is buried in sediment or soft tissues quickly decomposed leaving the hard bone or shells behind.
