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: Porbandar Calcarenite Member (Chaya Formation), Holocene (0.0 - 0.0 Ma)
• STRATIGRAPHIC RELATIONS: From Porbandar Calcarenite Mbr of Chaya Fm, which conformably overlies the Aramda Reef Mbr of the Chaya Fm (Late Pleistocene) and is unconformably overlain by the Katpur Fm (Middle Holocene). AGE: Chaya Fm is Late Pleistocene-Late Holocene, and with the Porbandar Calcarenite Mbr being the upper 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 Porbandar Calcarenite Mbr, which is the upper unit of the formation.
• member-level stratigraphic resolution
Environment/lithology: foreshore; poorly lithified, shelly/skeletal grainstone
Size class: macrofossils
