Also known as C. schultzei-type locality

Where: Eureka County County, Nevada (40.1° N, 116.0° W: paleocoordinates 22.5° S, 54.0° W)

• coordinate stated in text

When: lowermost Polygnathus asymmetricus conodont zone, Denay Limestone Formation, Givetian (387.7 - 382.7 Ma)

• “[T]he placement of the Red Hill I fish beds into the earliest Late Devonian (Johnson 1977: Leiorhynchus hippocastanea Zone [brachiopod interval 25] corresponding to earliest Polygnathus asymmetricus Zone [conodont]) corresponds to the placement of the boundary below the P. asymmetricus Zone. […] With the placement of the Middle/Late Devonian boundary above the earliest P. asymmetricus Zone, the fish occurrences were moved into the latest Givetian (Johnson et al. 1988). Murphy et al. (1976) had already given a late Middle Devonian age (upper Schmidtognathus hermanni-Polygnathus cristatus Zone). The conodonts occurring with the fish indicate a placement within the early Klapperina disparalis Zone, latest Givetian (Johnson 1990, fig. 52; Elliott & Johnson 1997; Elliott et al. 2000), which corresponds to the present day placement of the Middle/Late Devonian boundary.” Schultze 2010
