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
Size class: macrofossils
