Where: India (22.0° N, 70.5° E: paleocoordinates 22.0° N, 70.5° E)
• coordinate stated in text
• local area-level geographic resolution
When: Aramda Reef Member (Chaya Formation), Holocene (0.0 - 0.0 Ma)
• STRATIGRAPHIC RELATIONS: From Aramda Reef Member of Chaya Fm, which conformably overlies the Okha Shell Limestone Mbr of the Chaya Fm (Late Pleistocene) and is conformably overlain by the Porbandar Calcarenite Mbr of the Chaya Fm (Late Holocene). AGE: Chaya Fm is Late Pleistocene-Late Holocene, and with the Aramda Reef Mbr being the middle unit of the formation it is assigned here to a Holocene age. Age assignment based on combination of C and U/Th dates (numerous authors cited). STRATIGRAPHIC POSITION: From several beds throughout the Aramda Reef Mbr, which is the middle unit of the formation.
• member-level stratigraphic resolution
Environment/lithology: lagoonal or restricted shallow subtidal; poorly lithified, shelly/skeletal reef rocks
Size class: macrofossils
