Hike with Dinosaurs: A Guide to Arizona's Fossil Trail

Arizona is a treasure trove of natural wonders and fascinating geological formations. For families and kids who love dinosaurs and the outdoors, there's no better adventure than hiking along Arizona's Fossil Trail. This unique trail takes you through ancient landscapes where fossils from the Triassic Period (252-201 million years ago) are still embedded in the rock.

The Fossil Trail is a relatively easy 2-mile loop that starts at the Petrified Forest Visitor Center. As you hike, keep an eye out for stunning examples of petrified wood, which has been fossilized over millions of years. The trail takes you through a beautiful forest of saguaro cacti and juniper trees, providing ample shade from the desert sun.

Geology and Fossils

The Triassic Period was a time of great change on Earth, with supercontinents colliding and volcanoes erupting. As the landscape shifted, ancient rivers and lakes formed, depositing layers of sediment that would eventually become rock. Over millions of years, plant and animal fossils became embedded in these rocks, providing a glimpse into the region's prehistoric past.

As you hike along the Fossil Trail, look for signs of ancient sea life, such as ammonites and belemnites. These marine creatures roamed the Triassic seas, leaving behind their fossilized shells. You may also spot petrified logs, where ancient trees have been transformed into stone over time.
