Abstract:
The Gallatin Petrified Forest in Montana is a truly remarkable fossil resource, with layer upon layer of petrified forests preserved as upright trees dating back nearly 50 million years. The total thickness of these fossilized forest layers is more than 2,000 vertical feet! Erupting volcanoes that dotted the landscape during the Eocene Epoch, when giant, now extinct mammals walked the Rocky Mountain region, preserved these forests. This activity book will introduce you to the remarkable fossil resources of the Gallatin Petrified Forest, as well as the geologic history of the surrounding area. As you color the pages and solve the puzzles, you will learn about the remarkable geologic story of the Gallatin Petrified Forest.
