Where: India (22.9° N, 92.7° E: paleocoordinates 16.4° N, 93.2° E)

• coordinate stated in text

• local area-level geographic resolution

When: Upper Bhuban Formation (Surma Group), Middle Miocene (16.0 - 11.6 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).
