The Mesozoic era is often called the era of the dinosaurs. It lasted from about 252.2 million years ago (mya) to about 66 mya.[1] It is the middle of three eras that make up the Phanerozoic.

Its three periods are:

The Mesozoic era began and ended with huge extinction events. It began after the Permian–Triassic extinction event and ended with the K/T extinction event which killed the dinosaurs.

Before the Mesozoic was the Palaeozoic era, (Permian period). After it was the Cainozoic era, (Palaeocene epoch).
