The Mesozoic Era is the name for the period of time that began about 252 million years ago and ended about 66 million years ago. This era is divided into three geologic periods: the Triassic (from 252 to 201 million years ago), the Jurassic (201 to 145 million years ago), and the Cretaceous (145 to 66 million years ago).
This was an important time in the development of the earth and its inhabitants. Geologists believe that it was during this time that great tectonic plates under the surface of the Earth shifted, causing the supercontinent of Pangaea to break into two great continents first and eventually into all the different continents we now know. Great changes in animal life occurred also. Dinosaurs first appeared in the Late Triassic period and flourished during the Jurassic period, becoming the dominant land animals. They became extinct at the end of the Cretaceous Period. Birds, derived from a branch of flying dinosaurs, first appeared in the Jurassic Period. Mammals, distinguished from birds and dinosaurs by giving birth to live babies rather than laying eggs, first appeared during the Mesozoic, but most were small, none more than about 33 pounds.
The mass extinction at the end of the Mesozoic Era included not just the land dinosaurs, but about half the genera of animals then on earth ("genera" is the plural of "genus", as in genus and species). There may have been a major meteorite impact that caused this extinction and a series of violent volcanic eruptions may have contributed to it too.

When did mesozoic area begin?

What is the period of the mesozoic era?
The Paleozoic precedes the Mesozoic. And our current era, the Cenozoic, follows the Mesozoic.
What era began and ended with mass extinctions?
Paleozoic - climate change Mesozoic - meteor
What is the era before the Mesozoic?
The Paleozoic came before the Mesozoic.

Which was NOT a subdivision of the Mesozoic era?
The Cenozoic era was not a subdivision of the Mesozoic era. The Mesozoic era is subdivided into the Triassic, Jurassic, and Cretaceous periods.
What are two events from the Mesozoic era?
Events during the Mesozoic include the increasing dominance of dinosaurs. The Mesozoic is marked by the appearance of flowering plants.
What Era did dinosaurs live in?
The dinosaurs lived in the Mesozoic Era, which includes the Triassic, Jurassic, and Cretaceous periods. The first dinosaurs appeared in the late Triassic and went extinct at the end of the Cretaceous.
What dinosaurs lived in Mesozoic era?
The first dinosaurs evolved in the Mesozoic. At the end of the Mesozoic, all non avian dinosaurs became extinct. Therefor, all non avian dinosaurs, and some avian dinosaurs (birds), lived in the Mesozoic.
What life-forms dominated the mesozoic era?
Dinosaurs dominated over the mesozoic era.
