Arizona State Fossil – Petrified Wood

Petrified wood is ancient wood that has turned into stone over time. This happens when a tree gets buried by sediment and the organic material is replaced by minerals, usually silica.

Over a long time, the wood’s cell structure gets preserved, but in a stone form. So, while it looks like wood and even keeps the tree’s original patterns, it’s as hard as rock!

Among the many discoveries, these valuable rare Arizona fossils stand out as some of the most exciting finds:

Common Questions About Fossil Hunting In Arizona

We answer some of the most common questions people ask about fossils in Arizona:

Can you find megaladon teeth or sharks teeth in Arizona?

Arizona, known for its deserts and canyons, was once covered by ancient seas. Because of this, it’s possible to find fossils of sea creatures, including sharks.

However, finding megalodon teeth in Arizona is not common. Megalodon, a gigantic prehistoric shark, mostly lived in areas that are now the Atlantic Ocean and its surrounding seas.

Shark teeth have been found in the state. These are rare Arizona fossils, but they’re usually from smaller, ancient species, not the giant megalodon.

If you’re on the hunt for shark teeth in Arizona, look in places that were once underwater, like limestone and shale layers. Keep in mind, always get permission if you’re searching on private land or in protected areas.

Is it illegal to collect fossils in Arizona?

In Arizona, the rules about collecting fossils depend on where you are and what kind of fossils you’re looking for. On private land, you can collect common Arizona fossils if you have the landowner’s permission.

It’s always a good idea to get that permission in writing to avoid any misunderstandings later.

However, it’s a different story on federal and state lands. Collecting valuable rare Arizona fossils like those from vertebrates (like dinosaur bones or mammal remains) is not allowed without a special permit.

These permits are typically given to trained scientists for research purposes.

On the other hand, you can generally collect common invertebrate and plant fossils of Arizona for personal use on federal lands, as long as they’re not in national parks, monuments, or other specially protected areas.

Always double-check Bureau of Land Management guidelines and the rules of the specific area you’re in.

Some places, like national parks, don’t allow any kind of fossil collecting. It’s super important to respect these rules. They help protect Arizona’s rich natural history for everyone to learn from and enjoy!

Can you find dinosaur bones in Arizona?

You can find a variety of dinosaur bones in Arizona, from the mighty Dilophosaurus to the unique Sarahsaurus.

Then there’s the impressive Sonorasaurus, a massive long-necked giant, alongside the speedy Chindesaurus and the small yet interesting Segisaurus.

If you’re passionate about paleontology or just fascinated by the stories that rocks can tell, Arizona is a fantastic place to explore and learn.

How do you identify the fossils that you find?

First, look at the shape and size. Often, fossils have distinct patterns or features that hint at what they once were, like a leaf’s outline or the curve of a shell.

Next, consider the rock type. Fossils are commonly found in sedimentary rocks because they form from layers of sand, mud, and other materials that once covered living things.

Having a good guidebook on fossils can be super helpful. These books have pictures and descriptions to compare with what you’ve found. Using a magnifying glass can also give you a closer look at tiny details that might be key to identifying your find.

And remember, the area where you found the fossil can give clues. Different regions have different kinds of plants and animals in the past.
