Also known as Chiang Muan Basin
Where: Thailand (18.9° N, 100.3° E: paleocoordinates 17.6° N, 99.9° E)
• coordinate based on nearby landmark
When: MN 7 + 8 to MN 7 + 8 (12.8 - 9.7 Ma)
• "Middle Miocene": upper and middle lignite seams are in a normal polarity zone correlated with anything between chron C5ABn and chron C5n, but equivalent to "the top of... MN 8 and the base of MN 9" according to Pickford et al. 2004
• member-level stratigraphic resolution
Environment/lithology: mire or swamp; lignite and mudstone
Size class: macrofossils
Collection methods: specimens have "TF" museum numbers and clearly derive from different collections than the "CMu" material collected by the Japan-Thailand Paleontology Expedition from the Chiang Muan Basin
