What is the fossil?

Fossils are traces of ancient life and are used to find more about the history of life on Earth. The fossil can have a number of forms, from an ancient footprint in the volcanic ash to the body that has been converted into a stone in the process of perminerization. In natural history museums you can see numerous examples of fossils and many common fossils are also available to buy collectors and enthusiasts. In some areas of the world, you can also dig your own fossils. People have studied and wrote about fossils since the ancient Greeks noticed, such as things such as fossilized ocean organisms in mountain areas, and suggest that these areas could be underwater at some point. Collective information collected from millions of fossilies on Earth is known as a fossil record, and the fossil record provides a number of interesting traces in what life on Earth was once.

there are many gaps in fossil record because noEvery organism becomes fossilized. The conditions must be absolutely perfect to create a fossil; Otherwise, the body naturally disintegrates and disintegrates the gadgets and bacteria. Most fossils are formed because they are stored in damp sediments where bacteria cannot survive. Fossils were found in swamps, fast sand, clay, tar and volcanic ash

In some cases, fossils have a natural form. In the Roman city of Pompeyi, some excellent examples of natural forms were found, where the volcanic explosion killed many people by drowned them to ashes, mud and sediment. When the volcanic sediments were cooled and froze, they produced forms that surrounarušil the bodies of the victims. Over time, these bodies eventually disintegrated and left the fingerprints.

fossils can also be turned to stone if the conditions are correct. In these cases, highly mineralized water fills empty spaces in the body and minerals slowly concentrate and record the form of the organism in the stone. It isRelatively rare. In this way, many deep sea organisms were fossilized as they fell to the bottom of the ocean and were buried in the sediment.

Usually fossils are formed from parts of the animal that are mineralized, while the animal is alive, such as bones and teeth. These mineralized parts of the body are preserved by ideal natural conditions, while the meat decomposes and leaves behind a skeletal recording of the animal that was once. Rarely, the complete animals are preserved in the ice, as is the case with some Pliocéni animals such as mammoths.
