in the Jurassic period the atmosphere was about 14.7.
It looked like a sphere
Oxygen Levels were approximately 10% of what they are today. As photosynthesis only began in the Precambrian period the amount of carbon dioxide and oxygen in the atmosphere would be very small compared to modern times. In fact, human's probably wouldn't have been able to breath.
it was flat and dry with limestone
Buildup of carbon deposits led to surplus oxygen in the atmosphere. Oxygen built up in the Mississippian period and by the end of the carboniferous period, 35% of the atmosphere was oxygen. -nb
The Archean Eon was a period of time where the Earth was very hot and wet. The oceans were also very warm. Thousands of volcanic eruptions ejected volcanic ash that bombarded the earth and dust into the atmosphere causing violent lightning storms and continual rain. During this timeline the Earth atmosphere was polluted with enormous amount of Carbon and Sulfur dioxide concentration. Such levels of chemical content in the atmosphere would be very dreadful to the majority of living beings in the Earth today.
Warmer climate
it was the same but there was a groped land
awesome it rained mad hard
very hot <bitches must have been hot>
Marine creatures like sharks existed in the Jurassic. Marine reptiles like icthyosaurs, plesiosaurs, and thalattosuchians also existed. Thalattosuchians are fully marine reptiles.
The biggest dinosaur in the Jurassic period were the gigantic sauropods like the famous Diplodocus.
Like all dinosaurs, Stegosaurus lived in the Mesozoic era. It lived 150 million years ago. That was during the Jurassic period, the second period of the Mesozoic.
flat and even
there was no quarternary period, so make up a climate for your made up time period.
There was a minor extinction event at the end of the Jurassic period. It was probably caused by global climate change. Dinosaurs like Allosaurus, Ceratosaurus, Camarasaurus, and Stegosaurus couldn't adapt to the change in temperature, so they all died out. The Cretaceous period then came after the Jurassic period had ended.
well when i was there ,it was a litt;le bit hot
The Diplodocus was a dinosaur that lived during the Late Jurassic period. It was an herbivore it ate plants it was a large dinosaur it was much like the brontosaurus But it was more lizard like really tall
