The geological period in which dinosaurs appeared in large numbers was:

During the Permian period, the real dinosaurs were about to make their official debut.

It is known that dinosaurs ruled three geological epochs for a total of 165 million years. However, during the Triassic and early Jurassic periods, dinosaurs still did not become a very powerful species, almost completely dominating the entire evolutionary process of animals. By the end of the Jurassic period, very large sauropods had become the largest creatures ever on Earth.

The end of the Jurassic period was the peak of their domination of the earth, and they far surpassed other creatures of the same period in terms of diversity, intelligence, and size. How did the most legendary species in the history of the earth come to be, and how did it rise?

Before the advent of dinosaurs, lizard-type species had appeared on the earth, and although they were not as large as dinosaurs, they had a certain advantage over other animals at that time. Paleontologists believe they were the prototypes of the dinosaurs that came later. Lizards appeared in several geological epochs before the Triassic – the Carboniferous period (100 million to 100 million years ago).

At that time, what is believed to be the world's first reptile appeared: the Silothian lizard. By the Permian period, a geological epoch before the dinosaurs, reptiles were becoming more diverse and closer in shape to those of the earliest dinosaurs.

The Permian was a relatively arid era, and deserts were common. During the same era, lizards living in groups like the Ichirasaurus and Heterodontosaurus were active in desert oases. During the Late Permian, there were two distinct trends in the evolution of life, both of which had profound implications for the history of the Earth.

One of these trends is called dinosaurs, and the other is called mammals.

Just as Earth's evolution was in full swing, an asteroid larger than the meteorite that ended the age of dinosaurs 65 million years ago hit Earth at the end of the Permian period. The impact caused the extinction of most species, but it also served as a catalyst for the emergence of dinosaurs. During the Permian period, the real dinosaurs were about to make their official debut.

One of the earliest dinosaurs to appear, the Black Reisaurus was small and agile, quickly becoming a big winner in survival games. By the end of the Permian, the Cavinosaurus appeared, which was the prototype of many carnivorous dinosaurs and birds. Soon in the Jurassic period, the early Jurassic herbivorous dinosaurs began to evolve in size, and the advantage of size could help them escape the pursuit of carnivorous dinosaurs.

Hence the emergence of sauropod dinosaurs; The huge sauropod class pushed dinosaur evolution to its highest peak. Another reason for the emergence of large sauropod dinosaurs is the climate, according to geological records, the late Jurassic period was warm and humid, and dinosaurs could grow to more than 30 meters long. In addition, carnivorous dinosaurs have also become larger, more aggressive and threatening; For example, Allosaurus in North America.

In addition, very special dinosaurs, such as the feathered Chinese dragon bird, began to embark on the path of bird evolution. Under the influence of climate and living conditions, the end of the Jurassic period was the heyday of the Dinosaur Age.

The end of the Jurassic period was the pinnacle of their domination of the earth

Late Jurassic to Cretaceous period.

Hello, the main characteristics of the crustal movement in the age of dinosaurs are as follows:

1.The frequency of crustal movement was much higher than it is today, and crustal movement could occur every few thousand years, compared to once every few million years now.

2.The earth's crust was also much stronger than it is today, with the crustal movement of the dinosaurs pulling a continent apart, but now it can only pull a small island.

3.The movement of the earth's crust in the age of the dinosaurs could have pulled a continent apart, whereas now it can only pull a small island apart.

4.The movement of the earth's crust in the age of the dinosaurs could have pulled a continent apart to form a new continent, whereas now it can only pull a small island apart.

5.The movement of the earth's crust in the age of the dinosaurs could have pulled a continent apart to form a new continent, whereas now it can only pull a small island apart to form a new island.

6.The movement of the earth's crust in the age of the dinosaurs could have pulled a continent apart to form a new continent, whereas now it can only pull a small island apart to form a new island and form a new coastline.

7.The crustal movement of the dinosaur era could have pulled a continent apart to form a new continent, whereas now it can only pull a small island apart to form a new islet, and it will form a new coastline, a cavity and a new geological formation.

8.The crustal movement of the dinosaur era could have pulled a continent apart to form a new continent, whereas now it can only pull a small island apart to form a new islet, and it will form new coastlines, new geological formations, and new rivers and lakes.

9.The movement of the earth's crust in the age of dinosaurs could open a continent to the pins and form a new continent.

As you would like, the crustal movement of the Dinosaur Age had the following characteristics:

1.The movement of the earth's crust took place during the age of the dinosaurs, which was an important period of change for the earth.

2.The movement of the earth's crust has led to the formation of new topography on the earth's surface, with the formation of many new mountains, rivers, lakes and oceans.

3.Crustal movements have also led to changes in the Earth's interior, forming new geological formations such as volcanic, **, and mantle activity.

4.Crustal movement has also led to climate change, affecting biomes from the age of the dinosaurs.

5.Crustal movement also led to temperature changes on the Earth's surface, affecting biomes during the age of the dinosaurs.

6.Crustal movements also led to changes in the soil on the Earth's surface, affecting the living environment of plants and animals during the dinosaur era.

7.Crustal movements also led to changes in the geological structure of the Earth's surface, affecting biomes from the time of the dinosaurs.

8.Crustal movement also led to topographical changes on the Earth's surface, affecting the living environment of plants and animals during the dinosaur era.

9.Crustal movements also led to tectonic changes on the Earth's surface, affecting the biota community during the dinosaur era.

10.Crustal movement has also led to climate change on the Earth's surface, affecting biomes from the time of the dinosaurs.

The characteristics are as follows: the crustal movement in the Mesozoic can be divided into two stages: the Indosinian movement that occurred in the middle and late Triassic period and the Yanshan movement that occurred in the Jugmy Wheel Ra.

From the Paleozoic to the Mesozoic Triassic, China has been in a relative paleogeography of the South China Sea and the Northern Continent, but the Indosinian movement that occurred in the middle and late Triassic changed this paleogeographic form. As a result of the movement, the sea receded significantly and rose to land, and the Qinling trough folded into a mountain.

Are you going to ask about the geological period when dinosaurs formed? The geological period of dinosaurs is in the Mesozoic Era.

The Mesozoic Era was the era of reptiles on the earth, also known as the "Age of Dinosaurs".

The Mesozoic Era, about (67 million years) is the Jurassic period (billions of years ago), which can be said to be the era of the rise of dinosaurs, this period is the age of the life of huge sauropods and reptiles, and it can also be said to be the age of dinosaurs as overlords.

Dinosaurs appeared during the Triassic period.

During the Triassic, vertebrates were further developed. In the late Triassic, there are many species of sauropods and ornithischians, dinosaurs are already a diverse group, occupying an important position in the ecosystem Therefore, the Triassic is also known as "the dawn before the dinosaur generation".

According to the analysis of earth experts, continental drift can cause a series of environmental changes, which in turn can cause climate change. When the southern continents are separated, the newly formed ocean surface is also raised. As a result, all the seas are high and the sea expands to the land, and most of the land is covered by shallow seas.

The oceans have a huge impact on climate change, and when the ancient continents were not separated, the temperature on the earth was almost the same from the equator to the poles, and the temperature difference was not much different. However, in the late Cretaceous, the sea retreated, the climate changed, and the polar regions became colder, while in other regions, it became a temperate climate alternating between cold and heat, which provided external conditions for the extinction of dinosaurs adapted to the warm climate. The dinosaurs could not adapt to this change and slowly became extinct.
