Where: Utah (38.2° N, 111.2° W: paleocoordinates 8.1° N, 37.2° W)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Sinbad Limestone Member (Moenkopi Formation), Smithian (251.3 - 247.2 Ma)
• The Moenkopi Formation in southwestern Utah contains three limestone members. The lower limestone member, the Timpoweap is only very sparsely fossiliferous and is primarily a marginal marine deposit. The middle limestone, the Virgin Member, contains limestone units deposited under normal marine conditions during the Spathian trangression. The upper limestone, the Schnabkaib Limestone, is unfossiliferous and mainly evaporitic. These limestone members are separated by red members, informally distinguished as lower, middle, and upper.
• bed-level stratigraphic resolution
Environment/lithology: marine; lithified packstone
