Mesozoic Era:

The dinosaurs went extinct 65 million years ago. The Mesozoic Era lasted about 180 million years, and is divided into three periods, the Triassic, the Jurassic, and the Cretaceous. Each of these periods is divided into many epochs and ages.
Earth during the Mesozoic Era was much warmer than today, and the planet had no polar ice caps. During the Triassic Period, Pangaea still formed one massive supercontinent. Without much coastline to moderate the continent's interior temperature, Pangaea experienced major temperature swings.
During the Mesozoic, or Middle Life Era, life diversified rapidly and giant reptiles, dinosaurs and other monstrous beasts roamed the Earth. The period, which spans from about 252 million years ago to about

The Cenozoic spans only about 65 million years, from the end of the Cretaceous Period and the extinction of non-avian dinosaurs to the present. The Cenozoic is sometimes called the Age of Mammals, because the largest land animals have been mammals during that time.
Large snakes named Titanoboa, giant crocodiles, Cave lions, sabre-toothed cats, cave bears, giant deer, woolly rhinoceroses, and woolly mammoths were prevailing species of the Quaternary Period. Without the dinosaurs, plant life had an opportunity to flourish during the Cenozoic Era. Nearly every plant living today had its roots in the Cenozoic Era.
The climate was cold, and warm in some areas,and hotter near the equator like now.
The Cenozoic Era is divided into two periods, the Paleogene and Neogene which are divided into epochs. The Cenozoic has seen the extinction of the non-avian dinosaurs and the rise of mankind. It is marked by the Cretaceous-Tertiary extinction event at the end of the Cretaceous period and the end of the Mesozoic Era, and in the later cenozoic age animals were on the brink of extinction because it was getting too warm, and early humankind were already causing the animals to be in the endangered

    Where climate change is severe and the topography is flat, species would typically have to travel greater distances to find suitable conditions, experiencing greater risks of extinction” (Sandom et al 2014). Results have shown that late Quaternary climate change velocity was related with low modern species endemism of mammal’s amphibian and birds signifying that high extinction rates in the past was more prevalent in more climatically unstable regions. In a report done by Stephen Wroe and his team which studied how Climatic changes influenced the extinction of megafauna he documents how they “used mean annual temperature and annual precipitation anomaly and velocity between the past and the present to represent the…

    Scientists recognized during the late 1800’s and early 1900’s that there was some glacial and interglacial periods which may have correlated with the extinction of specific species. These scientists claimed that the extinction during the Pleistocene ice age may have been the ultimate reason why the large mammals went extinct. However, others disagree with this hypothesis due to the fact that there had been many glacial advances and retreats which had not resulted in the extinction of the megafauna; therefore, there is no reason that the last glacial event would have caused the extinction. The rebuttal to that disagreement, however, is that the mammals alive during the time of the earlier glacial events were different than the mammals alive during the later glacial…

    n the Carboniferous Period, specifically in the Pennsylvanian subsystem, between 323 and 299 million years ago, a substantial change occurred around the planet: the climate increased strongly so that oceans growed up more than two hundred meters above the level existed immediately before this period. The increase of the level of water allowed the developing and diversification of the first vascular plants, i.e., plants that alternate generations between the sexual gamete production (gametophyte) and the sexual stage (sporophyte). Through this period would have arisen three types of flora beyond red, green, brown algae, and ditoms: these are ferns, lycopods and sphenopsids (flora 1), the gymnospears, or vascular plants able for producing naked…

    Recently Earth has been slowing down the number of volcanoes erupting recently, but also a slow-down in sedimentation and a noticeable lull in tectonic plate movement. The Paleoproterozoic era was a significant time in Earth’s history. It was at this time when the atmosphere got its first taste of oxygen and also the first global glaciation event. But this was also a time where other uniformistisic routines shut down. Earth's mantle used to be much hotter than it is today and volcanoes allowed the mantle to cool over time, and geologic processes are thought to slow down.…
