Exploring Arizona’s Dinosaur Fossils: Legal Limitations Places to Find and Appreciation

Dinosaurs have long captured the imagination of people all over the world. Studying their fossils and footprints has given scientists a glimpse into their world and how they lived.

However, collecting fossils can be a complicated process due to legal limitations and restricted access to certain discoveries. In this article, we’ll explore the legal limitations for collecting fossils and the places to find dinosaur fossils and footprints in Arizona.

Legal Limitations for Collecting Fossils

If you’re interested in collecting fossils, it’s essential to know the rules. The Bureau of Land Management (BLM) oversees public lands in the United States, and they have specific rules in place for fossil collecting.

Before you start collecting, make sure you familiarize yourself with these rules. According to BLM regulations, you can collect common invertebrate fossils without a permit, as long as they’re on public lands and aren’t part of a protected area, like a national park or monument.

However, it’s important to remember that these fossils must be for personal use only. You cannot sell them or use them for commercial purposes.

Collecting vertebrate fossils, like those of dinosaurs, requires a permit. This permit allows you to collect fossils for scientific and educational purposes, and you must follow specific guidelines to ensure the preservation of the fossils.

It’s also important to note that collecting vertebrate fossils on Native American lands is strictly prohibited without permission from the respective tribe.

Restricted Access to Certain Fossil Discoveries

If you’re hoping to stumble upon a rare dinosaur fossil, you need to be aware that many discoveries are off-limits for collecting. This is especially true for vertebrate fossils and artifacts belonging to Native American tribes.

In the United States, the Native American Graves Protection and Repatriation Act (NAGPRA) was adopted in 1990 to safeguard Native American human remains, funerary objects, and sacred objects. The act mandates that remains and objects held by federal agencies and institutions that receive federal funding must be returned to the appropriate tribes upon request.

In addition to NAGPRA, the Paleontological Resources Preservation Act (PRPA) of 2009 prohibits the commercialization of vertebrate fossils found on federal land and restricts the removal of such fossils without a permit. These laws underscore the importance of treating fossils and artifacts with respect and understanding the legal guidelines for collecting them.

Places to Find Dinosaur Fossils and Footprints in Arizona

Arizona is a land of geological wonders. From the

Grand Canyon to the Painted Desert, the state is home to numerous sites that contain fossils and footprints of dinosaurs and other prehistoric life.

Let’s take a look at a few of these places:

Moenkopi Dinosaur Tracks

Located on the Navajo Reservation in Northern Arizona, the

Moenkopi Dinosaur Tracks offer a unique look into dinosaur behavior. The tracks, left in sandstone millions of years ago, show a procession of plant-eating dinosaurs crossing a muddy river flat.

The tracks were first discovered in the 1940s and have been preserved for visitors to see. It’s a great place to bring the family and imagine what it was like to walk alongside these giants.

Grand Canyon


Grand Canyon is known for its breathtaking views but also contains a treasure trove of fossils and footprints. The Kaibab Fossil Site, located on the canyon’s North Rim, contains fossils that date back to the Late Triassic period, about 240 million years ago.

The site also includes a dinosaur trackway that is one of the longest in the world. Additionally, ancient sea creatures have left their mark in the rocks, giving further insight into the history of the region.

Petrified Forest National Park

Petrified Forest National Park is home to one of the largest concentrations of petrified wood in the world and has served as a valuable site for dinosaur research. Within the park, you can see examples of Late Triassic flora, fauna, and geology.

The Painted Desert National Monument, located within the park, contains a number of dinosaur remains and is a favorite destination for fossil enthusiasts.

Indian Gardens Paleo Site


Indian Gardens Paleo Site, located in Southern Arizona, provides access to sea-bed fossils that date back nearly 75 million years. These fossils offer a rare glimpse into the marine life of the Late Cretaceous period and include mollusks, sea urchins, and shark teeth, among others.

For those interested in paleontology, this site offers an opportunity to dig and collect fossils firsthand.

Arizona Museum of Natural History

Finally, if you’re in the Phoenix area, don’t miss a visit to the

Arizona Museum of Natural History. The museum boasts an extensive collection of dinosaur remains and offers interactive activities for all ages.

The Southwest Paleontological Society, a group of amateur and professional paleontologists, is based out of the museum and offers lectures and field trips throughout the year.


Collecting fossils is a fascinating hobby that can offer insight into the history of our planet. However, it’s essential to understand legal limitations and respect restricted access to certain fossil discoveries.

In Arizona, there are numerous places to find dinosaur fossils and footprints, from the

Moenkopi Dinosaur Tracks to the

Arizona Museum of Natural History. By following the rules and guidelines, anyone with an interest in paleontology can enjoy exploring the state’s unique geological wonders.

Fossil remains offer a unique and fascinating look into the past, providing scientific data and historical insights that help us understand the evolution of life on Earth. Museums dedicated to fossil remains, like the Arizona Museum at Mesa, showcase these artifacts and promote appreciation of their importance and value.

Appreciation of Fossil Remains

Fossil remains have provided scientists with valuable information about the development of life on Earth. By studying fossils, scientists can piece together the history of life and the environments in which it existed.

This information has led to the development of new theories about how life evolved, and it has helped us understand the connections between various species and their habitats. While fossils have immense scientific value, their appreciation extends far beyond the scientific community.

They also have cultural and historical significance, representing a deep connection to our planet’s past. Fossil remains inspire wonder, curiosity, and imagination, igniting the imagination of people of all ages and backgrounds.

Museums Dedicated to Fossil Remains

One of the best ways to appreciate fossil remains is by visiting museums dedicated to their preservation and display. Museums often display fossils in interactive exhibits that engage visitors and help them understand the scientific significance of these artifacts.

The Arizona Museum at Mesa is one such museum that showcases a wide range of fossils from across the globe, including dinosaur fossils, plant fossils, and more. The Mesa museum also hosts a range of events and educational programs for visitors of all ages, making learning about fossils an enjoyable and entertaining experience.

These programs include guided tours, workshops, and interactive exhibits that allow visitors to explore fossils up close and personal.

Sharing with Other Rockhounds

Rockhounds, or collectors of rocks and minerals, are a community of individuals who share a passion for the world’s geological wonders. For these enthusiasts, finding and collecting fossils is a thrilling pursuit that offers a unique opportunity to connect with the planet’s ancient past.

Sharing collections and discussing discoveries with fellow rockhounds is a great way to deepen one’s appreciation of fossil remains. Whether it’s at a local rock and gem show or through online forums and social media groups, rockhounds can connect with other like-minded individuals to share knowledge and insights about fossils.

Additionally, participating in rock and mineral clubs or groups can offer opportunities to go on field trips to discover new fossil sites and expand your collection. These experiences not only deepen knowledge but also build community, allowing collectors to share their passion for fossils with others and inspire a new generation of rockhounds.
