Dinosaur Amazing Facts | Types of Dinosaurs

Dinosaurs were a species that populated the planet millions of years ago. They were prehistoric reptiles of all sizes, including gigantic ones that populated the planet earth during the so-called "Mesozoic Era". At the end of this era


Both dinosaurs and another large number of species became extinct although the causes are still unknown, but there are several hypotheses. Although many people think that all dinosaurs lived together at the same time, the truth is that the Mesozoic Era is divided into three periods. In the Triassic, between 254 and 204 million years ago it was mostly herbivorous dinosaurs that populated the earth, in the Jurassic, between 204 and 140 million years ago and in the Cretaceous, between 140 and 65 million years ago,  Contrary to what happens with the rest of reptiles,  dinosaurs were a type of reptiles with totally varied characteristics and very different between them.

While some dinosaurs were biped and walked on two legs, with short upper legs like claws, others were quadrupeds. While some dinosaurs were really slow, huge and excessively heavy, others were, although very large, totally fast and even other species were also small and totally light, using their speed to capture their food. Some used their speed to protect themselves from predators while others did so with their body, formed by very thick structures and almost impossible to cross. There were dinosaurs with horns, with beaks, with crests, with bones and even with feathers.

Characteristics of dinosaurs

Dinosaurs were animals that differed from the reptiles we know today since they walked with their legs under their hips. They did not crawl but walked, mostly, erectly. These living beings also had a hole in the area of ​​their skull located between the eye sockets and nostrils,  had sacral vertebrae in the pelvis and their extremities were located under their body. They also had muscles in the humerus and jaw and strong structures in the hips, knees, and ankles to move. 

Contrary to what happens with current reptiles, various theories and research suggest that dinosaurs did not control their body temperature according to the environment but instead used their own metabolism and that is why they could qualify, unlike reptiles, Like animals with some warm blood. Dinosaurs are divided mainly into two groups according to the structure of the pelvis. Some have it as reptiles and others as birds.

They can also be divided according to their eating habits into carnivores or herbivores,  although there were also species that consumed vegetables and various small animals or depending on whether they walked on two or four legs.

Extinction of the dinosaurs

Although today it is not yet known with certainty what could have happened so that the dinosaurs died out 65 million years ago, the theory that has a greater acceptance by the scholars of this extinct species is that it could be a Meteorite of a huge size, similar to that of a large mountain, which could probably come from a comet or an asteroid hit the earth brutally in what is now known as the Yucatan Peninsula, in the country of Mexico.    After the impact, it is understood that it opened in what is now the underwater crater of Chicxulub, which has about 200 km in diameter.

This impact, in addition to ending an entire era of reign in the land of these reptiles, it is estimated that 70% of terrestrial life was also taken ahead. Afterward, temperatures rose and many more living beings died as well. Those who survived died because of the rubble and debris that it caused. And if there were still chinks in life, the temperature dropped after the unbearable heat to thresholds that made it impossible for any living being to continue populating the earth. 

On the other hand,  other studies indicate that it was a large number of volcanic eruptions that caused the cooling of the earth, acid rain and the extinction of dinosaurs. If you want more information, you can read our article on meteorite theory and dinosaur extinction.

Types of dinosaurs

There are different ways to group the dinosaurs according to different characteristics but, mainly, the most interesting way to classify them is the one that distinguishes between saurischians and ornitisquios according to the way in which the hip of these reptiles was projected.  The saurischians were those dinosaurs that had a type of hip known as a lizard hip. This means that they had the pubic bone forward, just like lizards. This type of living beings arose in the Triassic.

Those that were not birds became extinct in the Cretaceous but those that were birds are considered as the ancestors of the current birds.  Dinosaurs that were carnivores or some gigantic-sized herbivores could be found within the saurisch.   Ornitisquios were the dinosaurs that had the type of bird hip. They lived between the end of the Triassic and the Cretaceous and had a kind of hip in which the pubis pointed backward. This makes them similar to current birds although it is worth noting that they do not derive from this type of dinosaur, but rather are related to the saurischians.

 All these dinosaurs were herbivores and lived in very large herds.  Even some of these types of living beings walked on all fours, using the backs to move and their body was stocky, with horns and hearts to protect themselves, although they were really peaceful animals.

Flying dinosaurs

Flying dinosaurs have been difficult for scientists to study since there have been few archaeological finds around this type of dinosaur. The flying dinosaurs were of different sizes and had very varied shapes. While some of them flew others simply limited themselves to planning and nesting in high areas, laying eggs. The sight of this type of animal was very good, to be able to hunt easily and above all they fed on fish and insects.  There were several species of this type of flying dinosaurs.

The Pterodactylus lived in the Jurassic and it was an animal of almost a meter of wingspan, with a kind of crest on the head, which is intuited that probably flew very well and had a good denture that allowed him to be a good hunter.  The Scaphognathus also lived in the Jurassic, and with a wingspan similar to the previous one, some research indicates that he lived and flew over what is currently Europe, as well as it is believed that he had a curious largemouth in the form of a bathtub.  The Pteranodon was a type of dinosaur that inhabited the earth during the Cretaceous and it is believed that it was one of the largest dinosaur-birds that existed, with almost two meters of wingspan.

These animals were probably flying very well and very fast, and although they had no teeth, they were probably great hunters who fed mostly on fish.  Finally, the Preondactylus was a type of dinosaur that lived during the end of the Triassic. It was a small living being, perhaps even more than a current pigeon, with small and effective teeth with which it hunted its small prey, and great capacities and lightness to fly quickly.

Carnivorous dinosaurs

But, really, the true predators among the dinosaurs were the carnivores as it has come to us today in a multitude of movies, books, stories and documentaries that have been responsible for trying to revive some parts of the reality of those prehistoric times such as It is believed that they took place, or even ficting some parts to allude to the ferocity of well-known dinosaurs such as the famous Rex, which, surprisingly enough, was not really the largest predator of its period. 

Carnivorous dinosaurs were on earth for 150 million years, so the number of carnivorous species is huge. Carnivores, which were predators or consumed carrion, can be divided into different groups according to the type of animals they consumed or how they hunted.  In the first place, omnivores are those that ate plants and animals and also eggs of other animals.  It stands out above all the Oviraptor, the dinosaur that is believed to consume more eggs of other species. The scavengers used to feed on corpses, which were not eaten by other predators or animals that died from natural causes.

They highlight for example the Dilophosaurus, although other predatory animals are also included that perhaps did not feel like running or putting themselves in danger by hunting.   The hunters in the pack were those who attacked a group of somewhat large herbivores. They attacked their prey jointly and lethally, sticking their teeth and claws and getting so they could not escape. On the other hand,  the largest and most feared dinosaurs, such as the well-known Tyrannosaurus Rex, used the ambush to catch their victims.

 According to their size, they even swallowed them whole, but if not, they bit them to death and then they were eating them little by little. If you want to know more, do not miss our list of carnivorous dinosaurs.

Marine dinosaurs

The marine dinosaurs were those that inhabited the sea during prehistory. Several studies conclude that marine dinosaurs were even more fierce than terrestrial ones, although this cannot be known exactly. Animals that lived in the sea or fell into the water could be prey to these predators quickly and without contemplation by the carnivorous marine dinosaurs.  

The two main specimens of this type of dinosaur were the Liopleurodon, which inhabited the land during the Jurassic, by the marine areas of Europe that measured about six meters, although it is known that fossil remains of specimens of up to 16 meters have been discovered of size. It was a very intelligent dinosaur that, although it was not fast, could get to eat its prey in a single bite if it decided to attack because it also had extremely sharp fangs.  The other specimen was the Kronosaurus.

This marine dinosaur was very aggressive and it is believed that it inhabited the area of ​​South America and Australia now about 100 million years ago. With about twelve meters in size, it considers that almost two people fit. Some studies consider that these animals left their eggs on the mainland, where no land animal dared to attack them since they had extremely sharp fangs,  so if they received an attack they could defend themselves by quickly eating their attackers, which would become His victims If you want to know more, don't miss our list of marine dinosaurs.
