Basic information
Sample name: Hang Mon 2
Reference: J. Prieto, P.-O. Antoine, J. van der Made, G. Métais, L. T. Phuc, Q. T. Quan, S. Schneider, D. N. Tran, D. Vasilyan, L. T. Viet, and M. Böhme. 2018. Biochronological and palaeobiogeographical significance of the earliest Miocene mammal fauna from Northern Vietnam. Palaeobiodiversity and Palaeoenvironments 98:287-313 [ER 4077]
Geography
Country: Vietnam
State: Son La
Coordinate: 20° 56' 9" N, 104° 22' 13" E
Basis of coordinate: stated in text
Formation: Hang Mon
Time interval: Early Miocene
Zone: MN2
Geography comments: "Sediments of the uppermost Hang Mon formation are exposed in an abandoned coal mine near Hang Mon village" that yielded Hang Mon 1, but the new site is from "along the road TL103 to the northwest of the village"
"The mammal biochronology is in line with palynology, suggesting a minimum age of 21.12 Ma (Böhme et al. 2011). In conclusion, mammalian biochronology and palynostratigraphy indicate an age of approximately 23 to 21 Ma for the composite fauna from Hang Mon, corresponding to the early Aquitanian (earliest Miocene)" (this is almost precisely MN2)

Environment
Lithology: siliciclastic (mixed)
Taphonomic context: overbank deposit
Habitat comments: "The central part of the exposure consists of a ~5-m-thick fanglomerate... at the contact with the grey clay and marl succession, a rhinocerotid maxilla with articulated P4-M2 was excavated"
the discussion indicates clearly that this is an overbank deposit
