Baranduz P19 (Oligocene of Iran)
Where: Iran (37.3° N, 44.9° E)
• Paleocoordinates: 28.1° N, 44.4° E (Wright 2013)
• coordinate stated in text
• outcrop-level geographic resolution
When: P19 foram zone, Qom Formation, Rupelian (33.9 - 28.1 Ma)
• formation-level stratigraphic resolution
Environment/lithology: marine; limestone
• medium- to thick-bedded limestones with abundant porcellaneous benthic foraminifera such as Dendritina rangi, d’Orbigny 1826 (Plate II, Figures 1 & 2); Penarchaias glynnjonesi (Henson 1950) (Plate II, Figure 5); Spirolina cf. cylindracea (Lamarck 1804) (Plate II, Figure 9); Peneroplis thomasi, Henson 1950 (Plate II, Figure 8); Austrotrillina spp., Borelis sp. (Plate II, Figure 6); Bullaveolina sp. (Plate II, Figure 7) and Praerhapydionina delicata Henson 1950 (Plate II, Figures 3 & 4). Associated assemblages of small benthic foraminifera are dominated by Triloculina tricarinata d’Orbigny 1826 (Plate II, Figure 10); Triloculina trigonula (Lamarck 1804) (Plate II, Figure 12); Textularia spp., Quinqueloculina spp., Spiroloculina sp. (Plate II, Figure 11); polymorphinids and valvulinids. Calcareous plankton is scarce.
