| Geographic resolution: | outcrop |
Time
| Period: | Permian | Epoch: | Guadalupian |

| Age range of interval: | 266.9 - 264.28 m.y. ago |
Stratigraphy
| Geological group: | Chapursan | Formation: | Panjshah | Member: | 2 |
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: Assigned to the early Midian on the basis of fusulinids Minojapanella and Lantschichites (although questionably identified). The overlying Kundil Formation contains Kubergandian (Roadian) fusulinids such as Cancellina and Praesumatrina (Flugel & Gaetani, 1991), although these are considered to be reworked by Gaetani et al. (1995). The Kundil Fm also contains conodonts assigned a Murgabian age by Gaetani et al. (1995), although the smooth-platform Mesogondolella species are challenging to use for biostratigraphy. An early Midian (late Wordian) age is retained here. | |||||
