Answer:

The permian period spanned the time between 286 million and 245 years ago.

Explanation:

Last period of the Paleozoic era, the Permian succeeded the Carboniferous Period and comprises the years from 286 million to 245 million years ago. It is subdivided into the Cisural (oldest), Guadalupian, and Lopingian (most recent) times.

It was during this period that the supercontinent Pangeia formed. With the immense concentration of land mass, the planet underwent a major climate change that made it drier, as there were rarely seas or rivers within the continent.
