The Jurassic period is integrated into the Mesozoic era along with other geological periods, the Triassic and the Cretaceous. Like all of these, the Jurassic began due to a sudden change in weather conditions and ended for the same reason. This geological period is divided into three sub-periods: lower, middle and upper.
The first began 200 million years ago, the second 175 million years ago, and the third 161 million years ago, ending 15 million years later.
The Jurassic period took place approximately 200 million years ago, during which time dinosaurs became the main predators on the planet.
At this time, the climate was very humid and the temperatures very hot. As a result , vegetation has spread significantly, becoming the food base of herbivorous dinosaurs. It should be noted that other dominant animals were flying dinosaurs. At the end of the Jurassic the first species of carnivorous dinosaurs appeared.
During the Jurassic the great continental mass of Pangea began to be divided into two great continental blocks: Laurasia to the north of the Earth and Gondwana to the south
According to the fossils found, paleontologists claim that during the Jurassic period the phenomenon of pollination was strengthened and this circumstance was fundamental to understanding the development of life on the planet. Jurassic
In the Jurassic period, dinosaurs became the most powerful animals, as the rest of the species did not pose any worrisome threat .
Curious data about dinosaurs
Some dinosaurs were no more than a meter long, while others reached up to 15 meters. It is not known for sure how long they lived, but it is estimated that some species reached 200 years. Most were herbivorous animals and carnivorous species could eat up to a ton of meat a day.
Interestingly, the largest animal that inhabited the Earth is not a dinosaur , but the blue whale. Small-sized carnivorous dinosaurs possessed remarkable intelligence . Although not exactly known, it is likely that they had intense colors like some reptiles. Some of them changed their skin like snakes. Jurassic
It is estimated that the fastest dinosaur could reach 40 km / h. In the territories of Argentina and China, many fossils of these animals were found and most were concentrated near the coasts.
Even though there is much controversy about its extinction, it is very likely that it was caused by an asteroid impact on Earth. However, not all dinosaurs have completely disappeared, as many have evolved into new species such as crocodiles. Jurassic
