Where: Oman (23.3° N, 58.5° E: paleocoordinates 27.1° S, 138.5° E)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Neseuretus tristani trilobite zone, Am5 Member (Amdeh Formation), Darriwilian (467.3 - 458.4 Ma)
• STRATIGRAPHIC RELATIONS: From the Amdeh Fm, which overlies the Hijam Dolomite Fm, and is overlain by the Saiq Fm. AGE: ?Dapingian–Darriwilian, Middle Ordovician; on the basis of chitinozoans; placed in Llanvirn to avoid orphaning. STRATIGRAPHIC POSITION: From the Am5 member. Identification of the trilobite Neseuretus tristani from
•Am5 in the Wadi Sarin area suggests close correlation with at least some part of the Hanadir Shale of Saudi Arabia, which has been tied into the Llanvirnian sections in Iberia and elsewhere in southern Europe (Fortey and Morris 1982; El-Khayal and Romano 1985) and which also supports an assignment to the Darriwilian (Lovelock et al. 1981; R. A. Fortey, unpublished data).
