Dinosaurs are fascinating and complex at the same time, appearing at different times and in different forms. Their very essence is a mystery and the differences between dinosaurs are quite impressive.
To understand this, different historians classify dinosaurs in different boxes, they have divided them into groups like other living species ! We will see different species such as the Tyrannosauridae which is powerful and fearsome, feared by all. Or herbivorous species such as the Hadrosauridae
(This section is a brief introduction to how dinosaurs are grouped. Scroll down if you just want to see a list of the different types of dinosaurs) !
The dinosaurs were grouped into different classes that scientists have found and given a name. They are all grouped by their physical characteristics as well as their family tree. This is a << classification >> !
Groups of animals start with large groups, for example, 'reptiles', then become smaller and smaller until there are 'genera', which are closely related species, and finally the individual species themselves (Genera is the plural of 'genus', a Latin word meaning 'origin', or 'type').
All living things are organized in groups. One of the largest types of groups is a "kingdom". You may have heard of the "animal kingdom", the group that contains all animals.
Dinosaurs, mammals, amphibians and humans are all part of the animal kingdom.
One of the largest families of carnivores of the Cretaceous period, tyrannosaurus are known as predators. Their senses were sharpened as well as their teeth to cut each of their victims.
The most infamous is the tyrannosaurus ex which is surely the best known of all dinosaurs because of its size, beauty and dangerousness !
It was a bipedal meat-eating family. The tyrannosaurus was of the theropod family and therefore looks like a bird of prey or a feathered dinosaur !
Examples of tyrannosaurus :
Sauropods were among the largest dinosaurs. A family of herbivores that did not attack other dinosaurs. Thanks to their size of more than 100 feet and their weight of more than 100 tons, they reigned over the Jurassic with their dominant character and incredible powers.
Not eating any meat, they did not hunt because they were herbivorous. They appeared in the Cretaceous period in the form of Titanosaurs.
Sauropods are very special and do not look like any other dinosaurs. They have a very large neck and a very long tail. They also had a very resistant skin. So you can understand why they were the herbivorous beings that could dominate other dinosaur races.
Examples of Sauropods :
The raptor is the most feared species of the Mesozoic era. They are close relatives of the modern bird family. Their appearance was very different from other dinosaurs, in fact the raptor is the most particular species according to us.
Adapted to stalk its prey, they have three claws on each leg in order to grasp, to claw the weakest herbivorous dinosaurs. With sharp fangs and a large jaw, it was probably the most cunning of all.
Raptors possessed the most advanced intelligence of the dinosaur era. They were cunning and very fast, their legs allowed great speed to catch fast prey. It is a species known today and there are many different forms of raptors.
Examples of Raptors :
As we recall, they are from the sauropod family. Their greatest peak was at the end of the Jurassic period, they were on all continents and had a very important breeding period. Their advantage in terms of survival made them one of the most growing species of dinosaurs.
At the beginning of the Cretaceous era, sauropods such as the Brachiosaurus were replaced by the Tytanosaurs. This time they come back more powerful. Still herbivorous, their bodies have mutated to have a thick layer of scales protecting them from mutilation and dangerous blows. Other factors such as size and appearance may have changed.
A feared species that could travel in herds as seen in some species in the jungle. Archaeologists have found the past presence of the Tytanosaurs in different places on earth !
Ornithomimids lived during the Mesozoic air. They were herbivorous beings and used to be in large flocks. Faced with the threat of carnivorous predators, they had to face this problem by creating tribes to protect themselves together from great risk.
They are the dinosaurs that were dug up first, because of their small size and countless corpses. For yes, this species had no great defense put to the sociability between their races.
The only peculiarity is the stains they have on their bodies, but they have no defense, horn or very sharp teeth, they are the species that have been hunted and killed for millions of years !
They lived in the hot regions of our planet. Having left traces in Africa, South America and Asia.
Abelisauridae is a family of theropod dinosaurs.
Spinosaurs are a family of bipedal meat eaters. They had unique physical characteristics, they had a long and very thin skull. Strongly resembling a crocodile, one can suspect that some members of this family such as the Spinosaurus and Baryonyx were known as great fish eaters and hunters.
The spinosaurus had a main sail on its back. Its name comes mainly from its spine. We recall that Spinosaurus means " spinal column lizard ".
Examples of spinosaurs :
Thyreophora is a large family of dinosaurs that lived at the end of the dinosaur extinction in the Tertiary Cretaceous period. Known to be dumb and very slow, their build pushes them to total defense.
A skin as hard as steel and tusks more and more built to resist all predators. armor, sharp points and heavy clubs.
The armament of this breed of Dinosaur has evolved over time and to perfect its art in order to defend itself in all situations.
Examples of Thyreophore :
A really strange appearance sheltered the Ceratopsians. In fact, it is known to everyone. The "Horned Faces" which includes familiar dinosaurs like the Triceratops and Pentaceratops easily recognizable by their enormous skull decorated with a short collar and horns and which measured one third of the total length of their bodies.
Most ceratopsians were comparable in size to elephants, but some species that were very common during the Cretaceous such as Protoceratops weighed only a few hundred pounds. The first Asian ceratopsians were the same size as the domestic cat.
Coelurosaurus means "lizard with hollow tail". Coelurosauria is a large group of dinosaurs that contains theropods that looked more like birds than Carnosaurs. Tyrannosaurs, including T Rex, were coelurosaurs.
They are therefore part of the predatory dinosaurs, real carnivores having an impact on fauna and flora.
Small precision: it is the only dinosaur still alive today. The Maniraptora group includes birds, the only group of dinosaurs alive today.
A race that evolved and found its name 20 million years before the total extinction of the dinosaurs. A very strange and peculiar race that was herbivorous and had a physique quite different from other dinosaur races.
This same race had attributes at its head, which allowed it to defend itself against predators, but also to take dominance against the alpha male in the tribes. As we recall, herbivorous dinosaurs used to stay in groups in order to survive against predators!
They had bones that stood out on all their faces, that's how they fought !
Towards the end of the Triassic, a new breed of small, unsightly, herbivorous dinosaurs appeared in the region of the world that now corresponds to South America.
The prosauropods were not the direct ancestors of the huge sauropods of the Upper Jurassic period but occupied a parallel and earlier branch in the evolution of the dinosaurs.
Strangely, most prosauropods appear to have been able to walk on two as well as four legs and there is some evidence that they could sometimes adopt a carnivorous diet
This kind of dinosaur belongs in principle to the theropod family - the bipedal carnivorous carnivorous dinosaurs, which includes tyrannosaurs, raptors, bird dinosaurs and ornitho-mimids.
The therizinosaurs were distinguished by their peculiar appearance with feathers, long scythe-shaped claws on the hands and a long neck.
Even more oddly, these dinosaurs seem to have followed a herbivorous (or at least omnivorous) diet in contrast to their strictly carnivorous cousins.
During the Mesozoic era, there was not just one missing link connecting dinosaurs to birds, but dozens: small feathered theropods that possessed a tantalizing mixture of dinosaur and bird traits.
Exquisite specimens of feathered dinosaurs such as Sinornithosaurus and Sinosauropteryx have recently been unearthed in China, prompting paleontologists to revise their theories about the evolution of birds.
Among the last and most populous dinosaurs to roam the earth are the hadrosaurs (frequently known as duck-billed dinosaurs), duck-billed ducks, and ducks. he large, low postured herbivores with hard beaks on their snouts to shred vegetation and sometimes had a distinctive ridge on their heads.
It is believed that most hadrosaurs lived in herds and were able to walk on two legs, and that some types (such as the Maiasaura and Hypacrosaurus) were particularly good parents for newborns and juveniles.
When talking about dinosaurs, it is important to remember that they have remained on Earth for tens of millions of years longer than humans.
This gave dinosaurs plenty of time to branch out and evolve into different types of dinosaurs. Dinosaur species had been appearing and disappearing for millions of years before the mass extinction at the end of the Cretaceous that killed the last non-avian dinosaurs.
After watching movies like Jurassic Park, it is easy to forget that not all types of dinosaurs lived together. Even dinosaurs that lived in the same period may have been separated for millions of years.
For example, 57 million years (or more) passed between the disappearance of the baryonyx walkeri and the appearance of the tyrannosaurus rex, but both species lived during the Cretaceous period.
Like all living animals, dinosaurs can be classified into different groups. However, all our knowledge of dinosaurs comes from fossilized remains that have been in the ground for an almost unimaginable period of time.
That is why, as we unearth more and more fossils, our understanding of dinosaurs, and the relationship between different types of dinosaurs, is continually changing.
