More About Fossils


Q: How old are Green River fossils?

A: Fossils found in the Green River Formation are historic relics of the long-ago Eocene Epoch and are typically between 40-60 million years old.

Q: What color are the fossils?

A: Fossilized fish range in color from light brown to dark black. The color of the surrounding limestone can vary from pure white or tan to mottled grey and brown. Random swirls and flecks of organic matter (including other small organisms) add to the uniqueness of each piece. The base color is ultimately determined by the sedimentary layer the fossil formed in.

Q: What size fossils are available?

A: Individual tiles average anywhere from 1″ x 1″  to 6′ x 6′.

Q: Are the fossils structurally sound?

A: Our fossils are cut thick enough for vertical and horizontal applications. Some uses may call for a backer board. But, in general, they are provided in dimensions that result in a sturdy and stable piece.

Q: Will a fossil fish backsplash stand up to cooking and splashes?

A: Yes. Properly sealed, a fossil backsplash can take anything from spaghetti sauce to bacon grease. In a horizontal application, such as a bar or island top, it may be wiser to preserve the fossils under several coats of high-quality polyurethane.

Q: Are fossil fish pieces expensive?

A: Considering their unique nature, fossil fish are surprisingly affordable as a design element for your home. The cost of a backsplash or countertop utilizing some of the more common fish — such as Knightia and Diplomystus — is comparable to a custom project utilizing high-end tile or stone.
