MV-10, Minersville, Mineral Mountains (Triassic of the United States)

Where: Utah (38.2° N, 112.9° W: paleocoordinates 8.7° N, 38.3° W)

• coordinate stated in text

• small collection-level geographic resolution

When: Thaynes Group, Spathian (251.3 - 247.2 Ma)

• bed-level stratigraphic resolution

Environment/lithology: deep subtidal ramp; lithified, shelly/skeletal grainstone

• Proximal storm deposits, which were colonized by large epifaunal bivalves during quiet phases. Accordingly, they most likely represent deposits of the middle shelf, between the mean fair weather wave base and the storm wave base.
• Bioclastic grainstone and rudstone intercalated with thin marlstones

Size class: macrofossils

Preservation: mold/impression

Collection methods: Repository: Palaeontological Institute and Museum at the University of Zürich (PIMUZ)
