Cherry Peak debris block, Bear River Range (Ordovician of the United States)

Where: Cache County, Utah (41.8° N, 111.6° W: paleocoordinates 8.1° S, 79.4° W)

• coordinate estimated from map

• hand sample-level geographic resolution

When: G2 or H trilobite zone, Garden City Formation, Floian (477.7 - 470.0 Ma)

• "Garden City Formation; trilobite zone uncertain, either G2 or H, early to middle Floian, late Early Ordovician"

• formation-level stratigraphic resolution

Environment/lithology: shallow subtidal; lithified, fine-grained grainstone

• "likely similar to the Fillmore [Formation], where a warm, shallow, storm-dominated, clear water environment is indicated(Hintze, 1973; Church, 1974)."
• "Debris block below a cliff face." "Specimen occurs on a fine well-sorted carbonate grainstone from a part of the section containing no other identified macrofossils." "Fine, well-sorted grainstone"

Size class: macrofossils
