Reptiles that ruled the Earth many millions of years ago

Although everyone has heard about dinosaurs, these amazing reptiles still hide many secrets. They reigned on earth in the Mesozoic era, throughout all its periods - the Triassic, Jurassic and Cretaceous. The mystery of their sudden disappearance has occupied scientists for many years and has given rise to many theories. Today we know that an asteroid led to their disappearance.

1

The first dinosaurs appeared at the beginning of the Mesozoic era, in the Triassic.

They evolved from the so-called reptilian primates, archosaurs, more than 200 million years ago.
2

Dinosaurs lived at that time in all regions of the Earth.

This was due to changes in the ecosystem that occurred as a result of the great Permian extinction. The ancestors of dinosaurs had freedom of movement and “conquest” of subsequent territories of the desert Earth.
3

The name dinosaur comes from Greek and means “terrible lizard.”

4

Dinosaurs were very diverse.

Although the first dinosaurs were not very numerous or diverse, as time passed and they became more dominant in the ecosystem, they began to diversify more and more. These reptiles have taken over land, water and air.
5

The first description of dinosaur bones was made in the XNUMXth century.

British naturalist Robert Plot included an illustration of a dinosaur bone in 1667 in his work entitled Natural History of Oxford. Interestingly, he described it as a giant's bone. In fact, it was probably the bone of a Megalosaurus, a large theropod from the Jurassic period.
6

One of the biggest scientific debates regarding dinosaurs is whether they were warm-blooded.

Currently, scientists are inclined to believe that dinosaurs were warm-blooded animals, although debate on this topic has been going on for many years. Interesting fact: reptiles, which include dinosaurs, are cold-blooded.
7

Dinosaurs have become famous in pop culture.

Michael Crichton's book Jurassic Park, published in 1990, made a great contribution to this. Three years later, the novel was made into a film by Steven Spielberg, which was a great success and had two sequels. Currently, the “base” created in the 90s is undergoing further expansion in the form of films from the “Jurassic World” series.
8

Dinosaurs probably had feathers.

This goes against the established image of these reptiles in pop culture, but the Velociraptor famous in Steven Spielberg's films was likely partially feathered.
9

The end of the reign of dinosaurs is called the Cretaceous extinction.

This phenomenon began about 65 million years ago and led to the extinction of the dinosaurs. It is also the boundary between the Mesozoic and Cenozoic eras, which continues today.
10

The asteroid led to the extinction of the dinosaurs.

Although there have been many theories about the extinction of the dinosaurs over the years, it is currently believed that the entire process was triggered by an asteroid impact. These findings led to the discovery of the 150 km wide Chicxulub crater located in Mexico. The asteroid impact not only caused fires and tsunamis, but also contributed to climate change, in particular a strong cooling of the Earth's temperature, which led to the disappearance of about 3/4 of the then ecosystem.
11

Modern dinosaurs are... birds.

Although this statement sounds absurd, scientists have discovered similarities between modern birds and theropods, including the famous velociraptors and tyrannosaurs.
12

The science that studies fossils, including dinosaur tracks, is called paleontology.

13

The most famous dinosaur skeleton was in the Natural History Museum in London.

It was an exact replica of the skeleton of a diplodocus named Dippy. The exhibit was in the museum hall from 1905 to 2017.
14

Patagotitan mayorum is considered the largest dinosaur.

Its name comes from the region where it was first discovered - Patagonia.
