• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Chorgali Formation, Lutetian (47.8 - 41.3 Ma)

• Lower Bhadrar Beds, now the Chorgali Formation, overlying the Sakesar Limestone (or sometimes considered an upper unit of the Sakesar). In the Salt Range, the Chorgali has been assigned to SBZ9 of mid-Ypresian age on the basis of benthic foraminifera (e.g., Sameeni & Hottinger, 2003; Sameeni et al., 2012). Ghazi et al. (2010) found Nummulites atacicus (SBZ8) and Assilina placentula (SBZ10). However, Bybell & Self-Trail (2007) assigned a younger, late Ypresian or early Lutetian (NP13, NP14, or NP15) age, to the underlying Sakesar Limestone on the basis of calcareous nannoplankton. The nannoplankton age, although not precise, is used here because dinoflagellates and nannoplankton from the Nammal Formation (beneath the Sakesar) indicate an NP11-NP13 age (Köthe (1988), Bybell & Self-Trail (2007)) that overlaps SBZ8-10.
