Where: India (22.9° N, 92.7° E: paleocoordinates 15.6° N, 94.3° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Upper Bhuban Formation (Surma Group), Early/Lower Miocene (23.0 - 16.0 Ma)

• STRATIGRAPHIC RELATIONS: From the Upper Bhuban Fm of the Bhuban Subgroup, Surma Group (Early-Middle Miocene), which presumably overlies the Middle Bhuban Fm and overlain by sediments of the Boka Bil Subgroup (Ganju, 1975).
