Chalheghareh, beds 98-106 [Qom Fm] (Oligocene of Iran)

Where: Iran (33.8° N, 51.7° E: paleocoordinates 32.1° N, 49.5° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Qom Formation, Rupelian (33.9 - 28.1 Ma)

• STRATIGRAPHIC RELATIONS: From Qom Fm, which overlies the continental Lower Red Fm. THICKNESS: Unknown thickness. AGE: Qom Fm is Early-Late Rupelian at this section, although collections originate from Late Rupelian strata based on planktonic foraminfera (pers. comm. Rögl). STRATIGRAPHIC POSITION: From beds 98-106, 320-340 m above the base of the section.

• group of beds-level stratigraphic resolution

Environment/lithology: poorly lithified, shelly/skeletal grainstone

• ENVIRONMENT: Shallow marine environment.
• SPECIFIC LITHOLOGY: Fossiliferous limestones (grainstones, packstones, rudstones). LITHIFICATION: Poorly-lithified, based on figured specimens.

Size class: macrofossils

Reposited in the NHMW

Collection methods: surface (float), surface (in situ),

• COLLECTOR: F. Steininger and M. Harzhauser (~2004). REPOSITORY: Museum of Natural History, Viena (MNHW).
