What is a fossil?

Fossils are the remains of a living thing or its biological activity covered by sediments that with time have been compacted and hardened, making its conservation possible until the present time.

And what is paleontology?

Paleontology is the science of the study of living things of the past, and includes studying fossils.

Searching for fossils

The finding of a fossil can be done in two ways; by chance or after studying the geologic maps. If, for example, we search for dinosaur eggs or a skeleton of an Iguanodon, it is necessary to look in the layers of the era in which the dinosaurs lived; in this case the Mesozoic, between 251 and 65 million years ago. On the other hand, if what we want to find are fossils of anthropomorphous and others primates near the evolutionary line of man, it will be necessary to search in more recent sediments, of less than 15 million years from the Middle Miocene to the present time.
