Fossils have given valuable clues to Earth's past, making them great collectible items. Paleontologists and collectors worldwide are constantly seeking hidden treasures with a strong interest in dinosaurs and other fossil giants, making them collectibles of great value. In order to be qualified as a fossil, an object must be at least several thousand years old. However, the oldest fossils have been determined to be about three and a half billion years old. A fossil is created when a plant or animal that died millions of years ago leaves behind a skeleton, bones, or other organic matter. When these bones or organic materials disintegrate or fall apart over a long time, they sometimes get preserved in a stone or petrified into a hard substance, allowing people to find their impressions or remnants. A fossil can be anything, from a preserved footprint to arthropods, fish teeth, mollusks, animal teeth, dinosaur bones, and plant fossils. Fossils can be preserved in ice, river sediment, volcanic ash, tar, desert sandstone, globs of hardened tree sap etc. They are often categorized as body fossils, remains of plants and anima
