What are the two most common fossils?

Palaeontologists people who study fossils divide them into two major types – body fossils and trace fossils. Body fossils show us what a plant or animal looked like. The first type body fossils are the fossilised remains of an animal or plant like bones shells and leaves.

What are fossils commonly found?

Most fossils are found in sedimentary rock. Sedimentary rock is formed by dirt (sand silt or clay) and debris that settles to the bottom of an ocean or lake and compresses for such a long time that it becomes hard as a rock. Limestone and sandstone are types of sedimentary rock that commonly have fossils.

How are fossils formed Class 10?

Fossils are formed in different ways but most are formed when a plant or animal dies in a watery environment and is buried in mud and silt. Soft tissues quickly decompose leaving the hard bones or shells behind. Over time sediment builds over the top and hardens into rock.
