Petrified Forest National Park
Petrified Forest National Park is known for its Triassic-aged fossils, especially its petrified trees. Less well-known are the reptile and other animal fossils found in the park. The Triassic was the period just before the dinosaurs ruled the earth in the Jurassic and Petrified Forest is the best representative of fossils from this period.
