The Archosaurs were considered the dominant land animals of the Jurassic Period. These include all non-avian dinosaurs, crocodilians, and pterosaurs. It is generally believed that their modern descendants are modern birds and crocodiles, alligators, caimans, and gharials.
jurassic The Triassic was the earliest period of the Mesozoic, followed by the Jurassic then the Cretaceous. The Cretaceous was of the greatest duration.
The Jurassic period is named after the Jura Mountains in Switzerland where significant geological strata from this time period were first studied. These rocks contain abundant fossils from the Jurassic period, which lasted from approximately 201 to 145 million years ago.
During the Jurassic period, the environment was warmer and had higher levels of carbon dioxide in the atmosphere compared to the present. The landmasses were generally located closer together, forming the supercontinent Pangaea. The Jurassic period had a diverse range of plant and animal species, including dinosaurs, which dominated the terrestrial ecosystems.
The Triassic Period occurred before the Jurassic Period. The Triassic Period lasted from about 251 million to 201 million years ago, while the Jurassic Period followed, lasting from about 201 million to 145 million years ago.
The Cretaceous period followed the Jurassic period and lasted from about 145 million to 66 million years ago. In the Cretaceous period, flowering plants became more dominant, dinosaurs continued to diversify, and large marine reptiles like mosasaurs thrived. However, the end of the Cretaceous period marked by a mass extinction event where dinosaurs and many other species went extinct.
Probably the most interesting sights during the Jurassic Period would be the plethora of dinosaurs. The world was dominated by these creatures at that time.
after Jurrasic period it is the Cretaceous period
The Middle Jurassic Epoch (175.6 - 161.2Ma) was in the Jurassic Period (199.6 - 145.5Ma).
During the Jurassic period, the atmosphere was warmer and had higher levels of oxygen compared to today. There were lush forests with a diverse range of plant and animal species, including dinosaurs and early mammals. The climate was relatively stable and supported the evolution of many iconic prehistoric creatures.
No, humans did not exist during the Jurassic period. This time period, which occurred about 201 to 145 million years ago, was dominated by dinosaurs and other prehistoric creatures. Humans did not evolve until much later, closer to about 300,000 years ago.
No!!! There were no people alive in the Jurassic period.
The Jurassic Period followed the Triassic.
The Allosaurus lived 150 million years ago. That was during the Jurassic period. The Jurassic period was part of the Mesozoic era.
jurassic The Triassic was the earliest period of the Mesozoic, followed by the Jurassic then the Cretaceous. The Cretaceous was of the greatest duration.
After the jurassic period started the Mesozoic Era.
The dinosaurs were the dominant land animals during the Jurassic and Cretaceous periods, rising to dominance during the late Triassic.
The Jurassic period is named after the Jura Mountains in Switzerland where significant geological strata from this time period were first studied. These rocks contain abundant fossils from the Jurassic period, which lasted from approximately 201 to 145 million years ago.
