Ethics of Collecting

What to Do if you Find a Fossil
Please remember, private collecting of rocks or fossils is prohibited. (Public Resources code 4307 and 5097.5)

Don’t touch it!
This may be difficult, but it’s very important. A fossil can tell stories about the time and place it comes from.  These stories are sometimes complex and once the fossil is moved, part of the story is lost forever. 

What Should I Do?
If you find a fossil, place a small pile of rocks nearby, or somehow mark its location so it can be found again. Jot down information about the specific location. What wash is it in? What is the nearest cross-road or wash? What other landmarks are around? How many miles is it to the nearest highway? If you have a park map, mark the location as best you can.

Next, call or stop by the Visitor Center to let park staff know about your find. Give them all of the information you’ve gathered. The Visitor Center staff will contact the park’s paleontologists who will return to the site as soon as possible. If you are staying in the park, the paleontology staff may ask you to return to the site with them.

What Happens Next?
The first thing the park’s paleontological crew will do is observe, measure and photograph the fossil. Next we will determine the exact location of the object, using topographic maps and aerial photographs. We also use the Global Positioning System for precise location details. Later, we’ll search the immediate area for more fossil remains.

Once the initial examination is complete, a detailed geologic study is made. We want to know what time period the sediment belongs to. How does it relate to other fossils we’ve found.? How does the fossil bed run, in what way is it tilting from the horizontal? How thick is the bed and how thick are the fossil beds above and below it? What color are the sediments? What is the sediment made of, pebbles, sand grains, silt, clay? We also check the compass orientation of the bone. All of these observations will help  us to reconstruct the animal’s habitat and lead to an understanding of the animal’s world and it’s lifestyle.

Finally , It Can Be Touched
Only once all of these data have been recorded, a professional crew will excavate your fossil find. Care will be taken to remove it exactly as it lays. Volunteers at the Stout Research Center will clean and repair the specimen.
