United Park City Mines property (Permian to of the United States)

Where: Utah (40.6° N, 111.5° W: paleocoordinates 13.8° N, 33.3° W)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Roadian to Roadian (272.3 - 264.3 Ma)

• Specimens are collected from float on slopes belonging to the Meade Peak Member (Phosphoria Formation, Roadian), but they may have eroded from the overlying Franson Member (Park City Formation, Wordian). Somewhat similar vuggy chert nodules have been observed in lower beds of the Franson Member in underground mine operations.

• group of beds-level stratigraphic resolution

Environment/lithology: offshore; lithified, phosphatic shale

• Park City in the type area is principally a relatively shallow marine carbonate sequence containing a phosphatic shale interpreted as a deeper-water tongue.
• Either phosphatic shale of the Meade Peak Member or limestone of the Franson Member.

Size class: macrofossils
