Where: Oman (22.5° N, 59.7° E: paleocoordinates 38.4° S, 55.2° E)
• coordinate stated in text
• local area-level geographic resolution
When: Kungurian (279.3 - 272.3 Ma)
• The limestone beds from WKJ-1 and WKJ-3 have been dated by fusulines as Kubergandian (=late Kungurian-early Roadian according to Angiolini et al. 2015) and WKJ-1 by conodonts (Mesogondolella zsuzsannae, Sweetognathus guizhouensis, Hindeodus excavatus) as Kungurian (Leven & Heward 2013; Lance Lambert pers. comm. in Fortey & Heward 2015), which means a late Kungurian age for WKJ-1 and a late Kungurian-early Roadian for WKJ-3. Indeed, the species Sweetognathus guizhouensis does not range to the Kungurian-Roadian boundary (Charles Henderson pers. comm. to Lucia Angiolini) so it is possible that the age of these outcrops is not younger than late Kungurian.
