Dinosaurs roamed the Earth in the Mesozoic Era, which is split into the Triassic, Jurassic and Cretaceous periods. They first emerged during the Triassic period around 245 million years ago. At the time, all continents were part of a single land mass – the supercontinent Pangea.
For over 130 million years, dinosaurs dominated life on land. They came in every shape and size, from feathery little carnivores the size of a pigeon to titans that stretched over 120 feet in length. But dinosaurs did far more than merely inhabit prehistoric floodplains, deserts and forests.

Frequently Asked Questions
What era were dinosaurs dominant?
Mesozoic EraThe Mesozoic Era is the age of dinosaurs. These animals grew so large they dominated the planet. Dinosaurs were so dominant that it took a catastrophic, environment-changing event for mammals to be able to take over.
What era did dinosaurs dominate the earth end?
Cretaceous PeriodDinosaurs went extinct about 65 million years ago (at the end of the Cretaceous Period), after living on Earth for about 165 million years.
Why did dinosaurs dominate the earth?
Thanks to the climatic catastrophe, those early, small dinosaurs were freed from their main competitors to become the dominant force in the animal world. ... The researchers zeroed in on rift basins preserving the CAMP to figure out precisely what happened to the climate and to plants and animals.
Did dinosaurs live on Pangea?
Dinosaurs lived on all of the continents. At the beginning of the age of dinosaurs (during the Triassic Period, about 230 million years ago), the continents were arranged together as a single supercontinent called Pangea. During the 165 million years of dinosaur existence this supercontinent slowly broke apart.
How long did the Dinosaurs dominate the Earth?
If you could rewind the clock 230 million years back, dinosaurs dominated the land. They didn’t reign for just for a short period of time. But they lived for over 175 million years.
When did the reign of dinosaurs come to an end?
In the Triassic period, a variety of dinosaurs ruled the land, sea and sky. Next came the Jurassic Period and is when the reign of dinosaurs reached its peak level of dominance. For the next 160 million years, dinosaurs were the reigning land vertebrates on Earth. This existed until the Cretaceous-Paleogene extinction.
How did dinosaurs survive the end of the Triassic period?
Jurassic Period (201 to 145 million years ago) At the end of the Triassic Period there was a mass extinction, the causes of which are still hotly debated. Many large land animals were wiped out but the dinosaurs survived, giving them the opportunity to evolve into a wide variety of forms and increase in number.
How did the sauropod dinosaurs change the world?
Back in the Early Cretaceous, between 135 and 130 million years ago, this part of the continent’s northern coast was covered in streams, swamps and lagoons. Large sauropod dinosaurs—think distant cousins of Apatosaurus —had to take care navigating between these mucky habitats, and as they did so they unknowingly changed the landscape around them.
