Fossils and its Types - Body, Molecular, Trace, Carbon Fossil
Fossils and Its Classification Introduction Fossil Fossils are the remains or traces of ancient life that have been preserved by natural processes, from spectacular skeletons to tiny seashells. Imprints, tracks and trails can also become fossilised, like dinosaur footprints or worm burrows. Fossilization The preservation of animal or plant parts is called fossilisation. This process involves all the fossil's physical, chemical, and biological aspects. A hard petrified form is obtained from the rock that has the bones of animals or plants part impression. Types of fossils 1. Body Fossils The first type, body fossils, are the fossilized remains of an animal or plant, like bones, shells, and leaves. These can be mould and cast fossils, like most of the fossilized dinosaur skeletons and big bones we see, replacement fossils, like petrified wood, or whole-body fossils – mammoths caught in the ice, or insects trapped in amber. 2. Molecular Fossils Molecu...
