Batain Coast south of Al Hadd, locality 2 (Permian of Oman)

Where: Oman (22.4° N, 59.8° E: paleocoordinates 41.2° S, 55.7° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Aseelah Unit Member (Saal Formation), Cisuralian (298.9 - 273.0 Ma)

• Permian limestone blocks in the Lower Triassic Aseelah Unit. Bryozoan assemblages most typical of Early Permian localities, but a Guadalupian and Lopingian age cannot be ruled out.

Environment/lithology: reef, buildup or bioherm; lithified bafflestone and lithified floatstone

• Textural endmembers of the calcisponge reefs are float- to rudstone, bafflestone, and framestone with sphinctozoan sponges, inozoan sponges, chaetetids, various bryozoans, crinoids, and brachiopods. Also, calcareous algae and smaller foraminifers occur.

Size classes: macrofossils, mesofossils

Reposited in the SMF

Collection methods: peel or thin section
