If today we can know what the dinosaurs were like, what types there were, what their habits were or directly how they became extinct, it was all thanks to the dinosaur fossils.

So, as without them this blog would practically not exist and nobody would know anything about its existence, today we are going to tell you all about these prehistoric bones.

Let’s travel back in time, specifically millions of years ago, thanks to the dinosaur remains available to science today.

What are dinosaur fossils?

The fossils are all the ancient remains of dinosaurs. When a dinosaur died, its body was devoured by other scavengers, leaving only the remains that could not provide any nutrients to said scavengers, such as bones, which are the most common fossils.

Besides dinosaur bonesthere are other very varied fossils such as the footprintsthe eggs or even the teeth. Of course, these three types of remains are much more difficult to find because their conservation through thousands of years of antiquity is more difficult than that of bones.

Unfortunately, Many of the dinosaurs that existed will never be found or known because all trace of them has been lost over the years. In fact, the chances of finding a fossil in good condition are very low, in addition to the fact that most are in such a state of deterioration that it is very difficult to obtain reliable information about them.

Even many times the parts real dinosaur fossils, are completed with synthetic parts. All in order to give the skeleton a more structured shape and understand its physiognomy a little more.

At least in Spain We are lucky to have, compared to other countries, quite a few dinosaur fossils, so if you want to see them live, all you have to do is read the article we have linked you to and visit their locations.

Types of Dinosaur Fossils

Let’s talk a little in depth about the four types of fossil dinosaur bones that exist, which are the most common to find and what kind of information scientists extract from them.

  • Bones: It is the hardest fossil and the one that most resists the passage of time, since it resists decomposition much better than soft parts, which decompose easily. For this reason, they are the ones we see the most in museums, in addition to being the most spectacular because they can form the entire body of a dinosaur.
  • Teeth: behind the bones, they are what is most found due to their hardness. Although most had different teeth, almost all of them are pointed and sharp in order to hunt other dinosaurs or crush vegetation in the case of herbivores.
  • Footsteps: after the hard parts are the most common to find. The problem is that it is not possible to know exactly which species has made each footprint if we do not find other fossils that give more clues, but at least aspects such as the behavior or distribution of the species throughout the Earth can be known thanks to the footprints. .
  • Eggs and nests: every dinosaur egg or nest that is found is practically a relic, since it is extremely difficult for any to have survived thousands of years. The eggs are very similar to those of birds, although they have varied shapes and sizes that can be up to 30 centimeters long or as thin and small as a pencil. On very few occasions there are even embryos inside the eggs.
  • Other fossils: other parts of the anatomy of the dinosaurs such as the skin, tail, claws or crests are even more difficult to find and their findings can be counted almost on the fingers of one hand. They are usually found attached to some type of rock that, luckily, has kept these remains over the years.

Paleontology as a science that studies fossils

The remains could never have been found, treated and cared for so that we would have them in museums if it were not for the paleontologists.

And you will ask yourself, but what exactly is paleontology? Well basically it’s the science that studies extinct animals in the prehistoric era of planet Earth.


paleontologists are in charge of examining all the fossil remains that appear, taking care of them and extracting them as carefully as possible so as not to lose any information from them. In addition, they are in charge of carrying out the reconstruction of the skeletons of the dinosaurs that we see in museums, so their work is practically like that of an artist.

If you love fossils and you are a fan of dinosaurs, without a doubt we recommend training in this profession, since there is no other that makes you closer to this extinct species.

Dinosaur fossils found in the world

can really be found fossil information in any country. since the dinosaurs were widely distributed throughout the world taking into account that the continents were united in the beginning, so we can find fossil remains throughout the world, not being more let’s review a little where fossils are found around the world .

  1. Venezuela: This is not a country very characterized by its fossil wealth, however, recently one of the most important finds in this countryit is the Tachiraptor admirabilis, the fossils found correspond to a small dinosaur of the order of theropods that dates back to the primary Jurassic approximately 201 million years ago.
  2. Colombia: This country is not characterized by being very rich in fossils, in fact the first fossil remains found were in 1990 and was recently described in 2015. This dinosaur was named Padillasaurus which was a Brachiosaurus, the fossil remains found were a pair of vertebrae.
  3. Argentina: In contrast to Colombia, Argentina is one of the most important countries when it comes to fossil finds. There are many fossils that have been found in this country. In this territory, one of the largest dinosaurs in the world, the great Argentinosaurus, was found.
  4. United States: The United States has also been an important area in terms of fossil finds, especially in its arid and mountainous areas, one of the most recent and important finds was made in California, where in the middle of a construction of a hydroelectric, remains of prehistoric animals were found; that although they are not the remains of dinosaurs in themselves, the large number of remains found ranging from Smilodons, sloths, camels and many remains of rodents is still impressive. Species very different from the current ones and which are believed to be the ancestors of those we see today.
  5. China: It has always been an important place when it comes to finding fossils, in fact recently a new dinosaur has been found which was found to have feathers and small wings, said dinosaur is related to Velociraptor and was named as Zhenyuanlong.
  6. Spain: Although long ago it was not a country with fossil riches, in recent times about 7 new species have been found dinosaur in that country. Ranging from the Concavenator, Arenysaurus, Titanosaurs, Arcanosaurus…etc. In addition, it is a cave where a large number of fossil remains of prehistoric animals were found.
  7. Germany: Another very characteristic area where fossils have been found is GermanyIn fact, one of the most recent and most interesting discoveries was that of the remains of a Megalosaurus hatchling. Remains that undoubtedly made a great contribution to what is known about these dinosaurs and all in general.
  8. Canada: Like other countries, it is a source of paleontological wealth, taking into account that said territory in the age of the dinosaurs was of a tropical climate, far from being a cold zone as it is now. One of the most recent discoveries in that country was that of a new species of dinosaur named Acrotholuswhich is considered one of the rarest dinosaurs that existed on earth.
  9. Mexico: In this country lies one of the evidence that supports the extinction of the dinosaurs by a meteorite, this theory states that a meteorite fell on earth and marked the end of the dinosaurs. The evidence would be the Chicxulub Crater, located north of the Yucatan Peninsula. Apart from this, a large number of dinosaur species have also been found.
