Shalamzar, Bk-2 unit, yellowish soft calcareous mudstone (Sh-20) (Miocene of Iran)

Where: Iran (32.1° N, 50.8° E: paleocoordinates 29.5° N, 49.1° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Bakhtiari Formation, Miocene (23.0 - 5.3 Ma)

• The precise dating of the Bakhtiari succession (within the Miocene) requires further highresolution taxonomic and biostratigraphic studies of the foraminifera and nannofossil species.

Environment/lithology: lagoonal or restricted shallow subtidal; calcareous mudstone

• 7 m thick package of very soft mudstones with diverse gastropods.
• mudstones

Size classes: macrofossils, mesofossils
