Answer:
Fossils are the geologically altered remains of a once-living organism and/or its behaviour. ... Fossils are of particular interest to geologists as they can help determine the age of a particular rock compared to other rocks, or identify the environment in which the rock was formed.
Fossils are formed in a number of 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.
Two methods to determine the age of fossils:
The fossils can also be dated by detecting the ratios of different isotopes of the same element in the fossil material. This process is known as radiocarbon dating. When living organisms change into fossils, their rate of radioactive C14 decay decreases slowly.
Answer:
Fossils are the remaining decaying part of the primitive animals as well as plants which are formed by the action of the microorganisms with due course of time. Fossils can may be vertebrate or invertebrate.
Fossils are used for the studying of inheritance.
