The geological history of North America comprises the history of geological occurrences and emergence of life in North America during the interval of time spanning from the formation of the Earth through to the emergence of humanity and the start of prehistory. At the start of the Paleozoic era, what is now "North" America was actually in the ...We infer that ridge subduction may have occurred in this region during Late Carboniferous to Early Permian. Combined with previous studies, there are two ridge subduction events during the early and late Paleozoic in Inner Mongolia within the southeastern CAOB, which coincide with two large-volume magmatic flare-ups (300 ± 20 and 450 ± 20 Ma).Create a timeline of major evolutionary events during the Mesozoic Era.

Mass extinctions occurred at the end of the Ordovician, the Devonian, and the worst one of all at the end of the Permian, when about 95% of all life on Earth died!

After the Permian Extinction wiped out over 95% of ocean-dwelling species and 70% of land species, the new Mesozoic Era began about 250 million years ago. The first period of the era was called the Triassic Period. The first big change was seen in the types of plants that dominated the land. Most of the species of plants that survived the ...Geologic Setting. Between 1.4 billion and 990 mya, volcanic activity, crustal rifting and filling of basins (formed by rifting) took place.

The third major mass extinction was during the last period of the Paleozoic Era, called the Permian Period. This is the largest of all known mass extinctions with a massive 96% of all species on Earth completely lost.

The Precambrian includes approximately 90% of geologic mammal. Mammal - Evolution, Classification, Adaptations: Mammals were derived during the Triassic Period from therapsids.
