There are two major schools of thought that can provide two entirely different answers to this subject. See the discussion section below for a Creationist's point of view on this answer.
Anyone knowing the current scientific answer to this can feel free to finish off this answer.
The Mesozic Era took place 251 to 65.5 million years ago (Mya) . It is separated into three geologic periods. From the oldest to the youngest,
Triassic (251.0 Mya to 199.6 Mya)
Jurassic (199.6 Mya to 145.5 Mya)
Cretaceous (145.5 Mya to 65.5 Mya)
The Mesozoic was a time of tectonic, climatic and evolutionary activity. The continents gradually shifted from a state of connectedness into their present configuration; the drifting provided for speciation and other important evolutionary developments. The climate was exceptionally warm throughout the period, also playing an important role in the evolution and diversification of new animal species. By the end of the era, the basis of modern life was in place.
The Mesazoic era began with the triassic period 248 million years ago, and finishing at the end of the cretaceous period 65 million years ago, with the Jurassic period in between.
fail question
Permian had started because boo thang
Mesozoic and Paleozoic
The Age of Reptiles refers to the Mesozoic Era.
The Rocky Mts. Formed and Pangea started to break apart

roughly 250 million years ago.
Mesozoic and Paleozoic
http://en.wikipedia.org/wiki/Mesozoic Btw, it's not the Mesozoic "area" but the Mesozoic era. Hope this was helfpul!
The Paleozoic precedes the Mesozoic. And our current era, the Cenozoic, follows the Mesozoic.
Paleozoic - climate change Mesozoic - meteor
The Paleozoic came before the Mesozoic.
Mesozoic Era
The Mesozoic Era is known as the Age of Reptiles.
mesozoic
Events during the Mesozoic include the increasing dominance of dinosaurs. The Mesozoic is marked by the appearance of flowering plants.
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.
