He concept from fossil comes from the Latin term fossĭlis, which translates as “What is achieved by digging” . Fossĭlis, meanwhile, comes from fodĕre (whose translation is "dig" ).

The fossils are known as remains of a organism and to the organic substances that present a certain degree of petrification . The fossils are naturally located in the various earth layers.

It can be said that fossils are vestiges of beings who lived in the past . These footprints (bones , eggs, etc.) are preserved converted into sedimentary rocks thanks to the action of minerals .

Fossil formation is called fossilization , a process that involves alterations in the structure and composition of the remains. When a animal It dies, its soft parts break down or are eaten by other species. The skeleton, on the other hand, may end up covered by sediments (such as clay, mud or sand) that protect it. The minerals that were part of these sediments are then dissolved by precipitation water. When the water evaporates, the minerals are deposited in the voids of the spongy tissue and finally harden, forming the fossil.

Those rocks that contain fossils can suffer the consequences of erosion and thus the remains are exposed. The science dedicated to fossil analysis is called paleontology .

A paleontologist Therefore, he looks for fossils in sedimentary rocks. Once the fossils have been found, they are unearthed and cleaned to proceed with their study. Thanks to paleontology, for example, you can know a lot about dinosaurs , animals that became extinct millions of years ago.

We often associate the concept of fossil with dinosaurs, but it is important to understand that there are fossils of different species , both animals and vegetables. In Canada, for example, the fossil of the oldest fish was discovered within the records, the Metaspriggina, since it dates to approximately 505 million years. Fortunately for scientists, the remains are so well preserved that they have been allowed to estimate much of the facial features of the species.

Another of the most relevant fossils is that of Megalosaurus, a genus of dinosaurs that lived in the Jurassic period, about 166 million years ago in present-day Europe, and probably also in Africa, Asia and America. In the year 1676, a group of excavators found a partial femur in England and it was examined by an Oxford professor, who initially said they were before the remains Of a human giant. It was only two centuries later that this fossil formally associated with a dinosaur and the species received its scientific name.

Since the 18th century, many European paleontologists have spent years digging up very peculiar looking bones near rivers and lakes. When the naturalist intervened Georges Cuvier , the puzzle was solved: they had discovered the fossil of Mosasaurus, a genus of sauropsids that inhabited parts of present-day Western Europe and certain regions of the American continent until approximately 66 million years ago. He was baptized in this way for having been found in the vicinity of the river Meuse.

In the video game series Animal crossing , developed by the Japanese company Nintendo , the player must control a human avatar who arrives at a village inhabited by animals and stays to live with them. In his day to day he has several possible activities, almost all of his choice, to lead a kind of second life in the game: he can choose to relax by the sea, gather fruits to sell them, plant various species of trees, fish or dig up fossils to donate them to Museum , Among many other things.
