MFI 89 Section (Miocene of Myanmar)

Where: Myanmar (20.1° N, 95.1° E: paleocoordinates 15.3° N, 95.5° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: upper Member (Irrawaddy Formation), Tortonian (11.6 - 7.2 Ma)

• "between 10.4 and 8.8 Ma" (chrons C5n to C4n or Tortonian) based on biochronology and entirely normal polarity of the section

• group of beds-level stratigraphic resolution

Environment/lithology: "channel"; ferruginous, nodular sandstone

• the "section is mainly composed of a succession of light-coloured sands and gray clays, with several ferruginous conglomerate nodules" and the Khoratpithecus specimen is shown as coming from a sandstone and said to be "from a channel deposit rich in iron-hydroxides in a nodular layer"

Size class: macrofossils
