What is a fossil?

A fossil is defined as the preserved remains or traces of ancient organisms. This preservation can occur in various forms, including bones, shells, imprints, or even traces like footprints or burrows left by living organisms. Fossils provide invaluable insights into the history of life on Earth, helping scientists understand how species evolved, the environments they lived in, and the ecological dynamics of past eras.

The preservation of ancient organisms occurs through various natural processes, such as mineralization, where organic materials are replaced or filled in with minerals, and amber, where organisms are trapped in tree resin. The study of fossils, known as paleontology, allows scientists to piece together stories of our planet’s biological heritage, contributing to our understanding of biodiversity and evolutionary patterns over millions of years.
