Hintze faunule J-5 from Ibex (Ordovician of the United States)

Where: Utah (38.9° N, 113.5° W: paleocoordinates 7.4° S, 83.0° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Wah Wah Formation (Pogonip Group), Blackhillsian (474.9 - 470.0 Ma)

• bed-level stratigraphic resolution

Environment/lithology: deep subtidal ramp; lithified, gray grainstone and lithified sandstone

• Mulitple sources indicate that this was a carbonate dominated ramp, with substantial siliciclastic input, below normal wave base, above storm wave base.
• Calcisiltite, medium gray, weathers light yellowish gray, quartz sandy, thin bedded slope forming.

Preservation: replaced with silica
