The Answer:
And, the answer for the the question is :
Explanation:
Palaeontologists estimate that the time period during which non-avian dinosaurs roamed the world ranged from 245 million to 65 million years ago. The Triassic Period lasted from 252 million to 201 million years ago, the Jurassic Period lasted from 201 million to 145 million years ago, and the Cretaceous Period lasted from 145 million to 66 million years ago. The Mesozoic Era was divided into these three time eras. During these epochs, the globe went through a number of phases of profound change, one of which was the disintegration of the supercontinent into a number of smaller land masses. Following that, temperature change had an effect on habitats and the availability of food, which in turn had an effect on the evolution of dinosaurs and other living things. There was a cataclysmic mass extinction catastrophe at the end of the Cretaceous Period, which is something that remains a mystery to a significant extent today. This event brought an end to the period of dinosaurs.
The era in which dinosaurs lived is known as the Mesozoic era, which spanned from approximately 252 million years ago to 66 million years ago. This era is divided into three periods: the Triassic, Jurassic, and Cretaceous periods, each of which was characterized by a unique set of geological and biological events.
During the Mesozoic era, the earth underwent significant changes. At the beginning of the era, the planet was still recovering from the largest mass extinction event in history, which had wiped out over 90% of all life on earth. In the aftermath of this event, new species began to evolve and adapt to the changing environment.
The early Triassic period was a time of great upheaval, as the continents began to shift and break apart. This led to the formation of new oceans and the rise of new mountain ranges. The climate was generally hot and dry, with extensive deserts covering much of the land.
By the middle of the Triassic period, the first dinosaurs had appeared. These early dinosaurs were small and relatively insignificant compared to the giants that would later roam the earth, but they were an important step in the evolution of these fascinating creatures.
The Jurassic period was a time when dinosaurs truly came into their own. This period saw the rise of giant sauropods like Diplodocus and Brachiosaurus, as well as fearsome predators like Allosaurus and Stegosaurus. The climate was generally warm and humid, with lush forests covering many parts of the earth.
The Cretaceous period was the final period of the Mesozoic era and saw the emergence of some of the most iconic dinosaurs of all time, including Tyrannosaurus rex, Triceratops, and Velociraptor. The climate during this period was generally warm and wet, with extensive coastal plains and shallow seas covering much of the land.
The end of the Mesozoic era was marked by another mass extinction event, which wiped out the dinosaurs and many other species. The cause of this event is still a matter of debate among scientists, but it is thought to have been the result of a combination of factors, including volcanic activity, asteroid impacts, and climate change.
the dinosaurs continue to fascinate and captivate people around the world. Through the study of fossils and other evidence, scientists are able to piece together a picture of what life was like during this incredible era, and gain a greater understanding of the natural world and its history.
