what was the cambrian period environment like compared to the present
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.
The Quaternary Period experienced fluctuating climate with multiple ice ages and interglacial periods, resulting in extensive ice sheets and glaciers. In contrast, the present environment is characterized by a warmer climate with less extensive ice cover and higher sea levels. Human activity has significantly impacted the environment in the present, leading to issues such as global warming and biodiversity loss.
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.
During the Precambrian period, which lasted from about 4.6 billion years ago to 541 million years ago, the Earth's environment was very different from the present. The atmosphere had little to no oxygen, the continents were still forming, and life was mostly single-celled organisms. The present environment is characterized by a more oxygen-rich atmosphere, complex multicellular life forms, and well-established continents.
grassy and naked
the carboniferous period had crinoids,echinoderms but today we don't have it
Warmer climate
after Jurrasic period it is the Cretaceous period
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.
The Middle Jurassic Epoch (175.6 - 161.2Ma) was in the Jurassic Period (199.6 - 145.5Ma).
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.
During the Carboniferous period, the environment was warm and humid, with vast swamp forests covering much of the land. These forests eventually formed the coal deposits we see today. In contrast, the present environment is cooler and drier overall, with different vegetation and ecosystems in place.
