Section 1 - continued next page. Fossils in section 1: - Chiefly in unit 5 - Tenucrediz americana and associate fauna which includes:- Ostrea Lunzia? In section 2 note that the lowest fossils include Pteris linguiformis and Ostrea - and that Tenucrediz fauna does not come in with these - but just above them. Note - so far no fossils in the banded beds below the Tenucrediz sand. Suspect banded beds a facies "shoreward" of P. linguiformis sands but where does Tenucrediz-Helmonites fauna fit in environmental set-up? Where is rich marine fauna of type area (Entry-Eagle Butte) sands in the Bullhead region? Does it come in to the east?
