Baba-Heydar, Shahr-e-kurd area (Eocene of Iran)

Where: Iran (32.4° N, 50.3° E: paleocoordinates 24.2° N, 44.3° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Pabdeh Formation, Priabonian (38.0 - 33.9 Ma)

• Crustaceans come from two distinct levels about 50 m apart, but the specimens are not assigned to levels in the paper. The age of this horizon is middle to late Eocene, based upon the pelagic and benthic foraminifers. Hantkenina compressa Parr, 1947, Hantkenina alabamensis Cushman, 1925, Marginulina wetherelli Jones, 1854, Bolivinoides draco (Marsson, 1878), Laevidentalina communis (d’oRbigny, 1826), Tritaxia aspera (Cushman, 1926), Lagena spp., Uvigerina spp., Operculina sp., and Nodosaria spp. belong to the middle to late Eocene (Coxall & Pearson 2006: 213), whereas Morozovelloides bandyi Fleisher, 1974 indicates an early late to middle late Eocene age (Pearson et al. 2006: 327). The lower part of the Pabdeh Formation is Priabonian age based on calcareous nannofossils (Senemari & Mejía-Molina, 2022).

• group of beds-level stratigraphic resolution

Environment/lithology: slope; lithified, argillaceous lime mudstone

• Petrographic and field studies of the Pabdeh Formation indicate that its sedimentary environment represents a deep sea environment which includes shale, pelagic lime and calciturbidite facies. Evidence from trace fossils, microfacies and analyses of turbidities suggests that the depositional environment of the Pabdeh Formation was a distally steepened ramp directed basinward towards the intra-shelf basin (Mirzaee-Mahmoodabadi et al. 2010).
• In the studied area, the Pabdeh Formation is about 800 meters thick and includes marls and gray shales, with intercalations of thin-bedded limestones (Fig. 2).
