ynot Posted February 22, 2018 Share Posted February 22, 2018 It is one of the fossil bearing layers of the green river formation. 3 Darwin said: " Man sprang from monkeys."

Fossildude19 Posted February 22, 2018 Share Posted February 22, 2018 The fish you commonly see for sale are from the "Split Fish Layer". This is lighter colored, softer matrix, that is more easily prepped. The "18 inch Layer" fish are in much harder matrix, but can be better preserved because of that.
