What is mesozoic era.

The era that dinosaurs lived in is called the Mesozoic Era. Within the Mesozoic Era, which began 251 million years ago and lasted 186 million years, we find 3 subdivisions in periods: Triassic. Jurassic and Cretaceous (from older to more recent). The Jurassic period began 200 million years ago and lasted 56 million years.The Mesozoic Era begins at the end of the Paleozoic.

In the Mesozoic, the plate boundary was a subduction zone dipping to the east under North America, and that shape is preserved as powerful evidence of the fundamental geometry of that boundary. The modern transform plate boundary, in contrast, is vertical. Further to the north and east, there are more terranes still.

The fourth major mass extinction was actually a combination of many, smaller extinction events that happened over the last 18 million years of the Triassic Period during the Mesozoic Era. Over this long time span, about half of all known species on Earth at the time perished.The end-Cretaceous extinction is best known of the "Big Five" because it was the end of all dinosaurs except birds (the non-avian dinosaurs). It also created opportunities for mammals. During the Mesozoic Era dinosaurs dominated all habitats on land.

Both life and ...Mesozoic mammals largely play by the same rules and can be largely identified using mechanical advantage values. Stem mammals are an exception: their angular process is anteriorly positioned (because they still retained a group of tiny bones in the back of the jaw, which eventually became the middle ear bones in later mammals) and thus have ...The Mesozoic and Cenozoic eras make up the youngest half of the Phanerozoic.
