What is a fossil?

Fossils (from Latin fossus, literally “having been dug up”) are the preserved remains or traces of animals, plants, and other organisms from the remote past. The totality of fossils, both discovered and undiscovered, and their placement in fossiliferous (fossil-containing) rock formations and sedimentary layers is known as the fossil record. These fossils are a rare occurrence but can be found all over. There are certain “Hot Spots” throughout the world, where a multitude of fossils can be found. These areas have allowed a very unique look at our planets preserved history. Some of the more notable fossil bed areas are in Europe, China, Russia, Africa, and the U.S.
