This is an uncommon set of 2 extinct herring ancestors along with a partial fish on a deeper layer in the same piece. The fish have been sealed with a clear preservative but their color has not been enhanced. Stand is included in the price.

If you wish to see the fossil fish bearing layers of strata in their native environment, check out Fossil Butte National Monument, Wyoming. Or, if you want to go and dig your own fossil fish, check out Fossil Safari, Kemmerer, Wyoming. I dug fish at this quarry for 12 years, had great success and hope to go back there soon.
