About Petrified Forest Field Institute

Petrified Forest National Park is deservedly known as one of the best records of Late Triassic paleontology and geology in the world. New plant and animal fossil discoveries, including Pseudosuchian and Ornithodiran archosaurs, dating back over 200 million years are found with impressive regularity. These finds are rewriting the Triassic fossil record and are continuing to expand our knowledge of this seminal time in the history of life on our planet. And you can be a part of it all!


Citizen science fossil digs are instrumental in assisting park paleontologists with the crucial work of excavation. There are two different dig experiences available to join. The One-day Fossil Dig Discovery and Excavation and a six-day overnight camping excavation and fossil survey called Paleontology in the Land of Color- A Fossil Survey of Petrified Forest National Park

Fossils found: Revueltosaurus, Aetosaurs, Shuvosaurids, Poposaurids and Rauisuchids, Crocodylomorphs, Pterosaurs, Silesaurids, Coelophysis, Chindesaurus and petrified wood

Period: Triassic

Formation: Chinle

All the digs featured on Ancient Odysseys are non-profits and rely upon visitors and donations to continue their important scientific work. Please consider donating if you would like to support this organization's mission. All donations are tax deductible.

 One-Day Fossil Dig Discovery + Excavation at Petrified Forest Field Institute | What's Included

Join a dig at Petrified Forest!
  • June 15 or August 10, 2024

  • 8am-4:30pm

  • $165 per day

  • 14+ (minors must be accompanied)

  • Limited to 10 participants per session

Prepare to get dirty digging in the Triassic Chinle Formation for fossil bones of giant amphibians, reptiles, and even early dinosaurs. Join Adam Marsh, lead paleontologist at the park for this one-day introduction to paleontology field work.

You’ll start the day with a behind the scenes tour of the park fossil collections and then be driven ‘off the beaten’ path to work for about five hours at the research quarry and dig site. While there, participants will work closely with park paleontology crew to learn to identify fossils from rock and carefully excavate specimens.

This is a real-life adventure where participants participate in a real paleontological dig. That means you’ll be working on your hands and knees in the dirt using light hand tools and brushes, but there is no heavy digging or lifting. Depending on what the day turns up, you could be casting fossils to carry out using plaster and burlap.


Any and all collected specimens become part of the park’s museum collection!

 Six-Day Paleontology Dig in the Land of Color with Christa Sadler | What's Included

Christa Sadler leading a 6 day paleontology dig at Petrified Forest
  • May 5-10, 2024

  • $650

  • Adults only or minors 15+ with special permission

  • Limited to 8 participants


Join Petrified Forest National Forest paleontologist Christa Sadler for an exploration of the paleontology and archeology of some of the newly acquired park lands. This is a car camping expedition in a remote area of the park where you will prospect and look for new fossil sites and excavate fossils at known localities. You will have a chance to learn prep work in the paleontological lab and have time to explore the region for petroglyphs, incredible scenery and whatever else we discover.


During the course of our six days, you will also learn about:

  • Regional geology and Mesozoic stratigraphy and relations to other Late Triassic formations worldwide

  • An overview of the Permian-Triassic extinction and Mesozoic paleontology

  • Timeline of prehistory at Petrified Forest NP

What to Expect

This is an overnight tent camping expedition, during which you will be an active participant in paleontological prospecting, excavation, and fossil preparation techniques. These are full of hiking, working and surveying. The temperatures during the day will be in the mid-90s and at night in the high 50s.

  • Day 1: Meet at the Rainbow Forest Museum for an introduction to the geology and paleontology of the region and the park. After lunch, we will take a short hike to some of the popular areas of the park. Later in the afternoon we will move to our base camp.

  • Day 2: This morning we’ll work in the paleontological lab and collections and take another hike in the afternoon

  • Days 3-4: Excavations and prospecting all day!

  • Day 5: A day of excavating paleontology and prospecting for archaeology!

  • Day 6: We’ll move to the paleontology lab, where we will have a chance to learn fossil preparation techniques and finish up around lunchtime.

An interview with Adam Marsh, PhD| Lead Paleontologist | Petrified Forest National Park

Adam Marsh Petrified Forest_edited.jpg
  1. What makes your site significant?
    These sites have produced Triassic fossils that represent the earliest frogs in North America, the first records of certain fish and reptile species outside of the Eastern Hemisphere and Antarctica, and the world's oldest caecilian.

  2. What has been most surprising about your discoveries at this location?​
    These sites are so fossil-rich that virtually anyone has the chance to make an important discovery any time we visit them.

  3. What are your current research objectives at your site? 
    We are seeking to understand more about the small-bodied animals living ~220 million years ago during the Late Triassic. Like today, the vast majority of vertebrate biodiversity in the Triassic came from small animals, but these are often under-represented in the fossil record due to their fragility and the lack of previous collections efforts.
