Golden age of dinosaurs was during

The Mesozoic Era is literally the era of middle life. It is also known as the age of dinosaurs. It lasted from 245 to 65 million years ago and is divided into the three periods. The Mesozoic began with the supercontinent Pangaea. Then, during the era, Pangaea broke up and the continents drifted apart. The movement of continents changed climates. It also caused tremendous volcanic activity. Mass extinctions occurred at the end of the Triassic and Cretaceous Periods. The first extinction paved the way for a dinosaur takeover. In the second extinction, the dinosaurs finally disappeared.
