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.
How do we classify fossils?
Once the fossils are prepared by scraping and cleaning they are sorted by geometry. Fossils with very similar geometry are assumed to belong to a single species. Fossils with somewhat different geometry are assumed to belong to a different species. Usually the fossil species has already been studied and named.
