The Triassic period.     The Triassic period was the first part of the mesozoic era .It took place about 200 to 250 million years ago, with the weather back then being mostly dry and hot.The continents was still connected in one piece until the mid Triassic period where it broke off and began to separate into two pieces.Although there were dinosaurs during the triassic period, they did not become dominant until the Jurassic and cretaceus period.
