What we do

Prepared Fossils

Available framed and unframed. We carry an extensive selection of Green River formation fish species in a wide range of sizes and pricing. New items are always being offered for sale.

Other Prepared Fossils

While fossil fish specimens are the most common, we also recover plant life and other vertebrate and non vertebrate specimens. Our selections is quite extensive and unique – one of the best in the world!

Educational Preparation Kits

For the student, hobbyist, or interested individual. Our kits include all materials and tools needed, clear directions for specimen preparation, and brief background information on the specimen itself. 

Quarry Trips!

Want to dig your own? We have quarry trips that are suitable for all ages (except small children), our quarry digs are exciting and rewarding. There is nothing that quite compares with the thrill of uncovering a 60 million year old fossil!

About Us

Ulrichs’s Fossil Gallery features some of the finest prepared fossil fish specimens ever found. Fish fossils from Ulrich’s quarry reside in museums worldwide, yet they are also available for sale to the public, in fossil preparation kit form, or as a dig-your-own adventure with a member of our staff. For more information, please give us a call at the Fossil Gallery!

Our Vision

The fossils prepared by Carl Ulrich and the staff of the Fossil Gallery are among the finest available. Carl’s prepared fossils are very much in demand by serious collectors and museums. As we often get requests to these amazing fossils, we have also made them available for customers to take home as beautiful additions to your home.

Some Fossils You May Encounter

These are just a few of the fossils you may dig up at our quarries.
The most common and widespread fish genus found within the deposits of Fossil Syncline Lake is the Knightia, a herring-like fish. Knightia rarely exceed ten inches in length and are found throughout the formation. 
Another common and widespread genus found in the Green River formation. The largest herring genus in the ancient lake deposits is the Diplomystus. It can be distinguished from the Knightia by the presence and pattern of scale rows or scutes that lie along the midline of the back from the skull to the dorsal fin. The deep bodied form and elongate anal fin are easily recognizable traits of this fish. 
Not as common as Knightia and Diplomystus; the Priscacara is a spiny-rayed member of the Lake fauna that has been previously been assigned taxonomically to various families, which include the perch and bass. Recent work has placed the Priscacara into its own family called Priscacaridae. Contemporary forms of the oval shaped genus occupy the upper regions of freshwater lakes and ponds, sunning themselves and feeding. 

What To Expect

Because our quarries are at 7200 feet in elevation, quarrying does not begin until June.

We do ask that you make advanced reservations, as we have one of our knowledgeable staff with you at all times.

We furnish all tools and other equipment necessary for excavating, including transportation from the Fossil Gallery to the quarry. You provide your personal amenities such as camera, glasses, mid morning snack or whatever you think you may need in the few hours you will be digging. We highly recommend wearing sunglasses, as the glare on the top of the mountain can be severe.

We quarry seven days a week, weather permitting leaving from the Fossil Gallery at 9am unless special arrangements are made. The total length of the trip is about 3 hours.

You are allowed to recover 6-8 complete fish, which you can easily do in the time allotted.

We suggest that you wear layers as it can be quite cool in the early morning, then turn very warm before we return.

A $90 fee allows you to collect all common specimens except those designated as rare and unusual by the State of Wyoming to include stingrays, garfish, birds and all mammals. You would be allowed any and all sizes of Mioplosus, Phareodus, Priscacara, Knightia, Diplomystus, Notogoneus. The fee also includes having your material cut (squared) by our staff on your return from the quarry. Packing material is provided.

Some History

Mass Mortality

Mass Mortality

Some of the first fossil fish from the Green River Formation were collected by geologist Dr. John Evans in 1865 and described scientifically by Joseph Leidy. Not all early collectors were scientists, Union Pacific Railroad workers discovered the Petrified Fish Cut near Rock Springs station in the 1960’s. A few years later the railroad was routed near Fossil Butte. Other collectors were men and women, sometimes whole families, fascinated by the fossils they found. Robert Lee Craig, who quarried fish from Fossil Butte and Fossil Ridge to the south, spent 40 years (1897-1937) quarrying and preparing fish from museums and private collections throughout the world. David C. Haddenham worked the Fossil Butte sites for more than 50 years.


unframed (rare)
Many of the countless fossils the Ulrich’s quarried and carefully prepared are studied and exhibited today in museums across the United States. Some of these include, the Field Museum in Chicago, the American Museum of Natural History in New York, the University of Wyoming Geological Museum at Laramie, the Museum of Natural History at Salk Lake City, and the Smithsonian Institutions National Museum of Natural History in Washington, D.C.. The extensive collections reflect the toils of private and scientific collectors of the past 100+ years.

A Unique Experience

We are proud that Carl Ulrich’s unique method of preparation and presentation has allowed many of his works to be shown worldwide, not only as scientific interest, but also as an art form. A few of his rare pieces can be found:

  • Museum of Natural History, New York, New York
  • University of Wyoming Museum and Geology Department
  • Smithsonian Institute, Washington, D.C.
  • Fossil Butte National Monument, Kemmerer, Wyoming
  • Rutgers University
  • Princeton University
  • U.S. Embassy at Guatemala

The present Ulrich Quarries originated in 1947 as an avocation of Carl and Shirley Ulrich. They serve as a preservation and gallery in Fossil, Wyoming and are the full time responsibility of the Ulrich’s. The delicate fossils that are found are carefully prepared, cataloged, researched and displayed for all to see.

These quarries are the original and legal commercial sites producing unprepared fossils. The preparatory at the Fossil Gallery serves as the the center of Carl Ulrich’s meticulous hand preparation process. Hours of remarkable dexterity arid accuracy with scribes expose the detailed fossil. Ulrich fossils are the finest in the world, representing a philosophy of creative utilization and preservation of the fossil of fish, plants and other organisms of the Eocene Age in a fresh-water lake system extinct for 50 million years.
