Bagmara - Baghmara Fm (Miocene of India)

Where: India (25.2° N, 90.7° E)

• Paleocoordinates: 12.9° N, 89.6° E (Wright 2013)

• coordinate stated in text

• outcrop-level geographic resolution

When: Baghmara Formation, Early/Lower Miocene (23.0 - 16.0 Ma)

• STRATIGRAPHIC RELATIONS: Assumed by Hendy (2007) to originate from the Baghmara Fm, which regionally conformably underlies the Chengapara Fm (Burdigalian). AGE: Aquitaian-Burdigalian. STRATIGRAPHIC POSITION: From unknown position within formation

• bed-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; poorly lithified, fine-grained, shelly/skeletal marl and lithified, concretionary sandstone

• ENVIRONMENT: Depth of "thirty fathoms", therefore assigned in a relatively shallow water environment.

• SPECIFIC LITHOLOGY: Soft, fine-grained, bluish grey shell marl, and in the intercalatory concretionary sandy hard beds. LITHIFICATION:

Size class: macrofossils

Preservation: original aragonite, original calcite

Collected by Mukerjee in 1924; reposited in the BMNH
