Origin: These Knightia fossils were quarried on private land in Wyoming, and date back to about 55 to 35 million years ago!

Knightia were freshwater fish that lived in North American lakes during the Eocene, and likely fed on other small fish and algae. They are one of the most common fossils found in the Green River formation, which spans modern day Colorado, Utah, and Wyoming. This area is famous for its sedimentary deposits and fish fossils that give paleontologists a peak into our not-so-distant past.

Sometimes, while digging in the Green River formation, paleontologists find abnormally high amounts of fish fossils. These layers are known as “mass mortality layers” and usually indicate some sort of external force that caused a mass death in the fish population!

Each fossil is in good condition, although minor damage and repairs are to be expected. A small acrylic display stand and a Certificate of Authenticity is included.

Actually, many relics are able to be owned by anyone.

Typically, museums only want to display items that are either very rare or incredibly well preserved. This leaves many items that don't make the cut, and these are able to be owned by individuals.

While the items we sell aren't "museum grade," they still carry with them the same amount of history and uniqueness. Each relic was still hand made by a person, hundreds or even thousands of years ago.

One of our core values is not to damage or alter any of the artifacts we sell.

History needs to be preserved—after all, there is a limited amount of it that survives—but it is also something to be shared with the masses. For this reason, we put our relics in sturdy display cases that are safe to handle, but are mindful that someday the relic may need to be taken out again.

No glue or resin holds the items in place. Instead, we're developed our own method for holding the relics securely in their displays using pressure alone. In fact, any of our relics can be removed in their original condition by simply opening the display case.
