Rangitikei River, Waiomio Shellbed (Pleistocene of New Zealand)

Where: Wellington, New Zealand (40.0° S, 175.5° E: paleocoordinates 40.0° S, 175.5° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Waiomio Shellbed Member (Waiomio Formation), Middle Pleistocene (0.8 - 0.1 Ma)

• basal OIS 15, ~ 550-600 ka

• bed-level stratigraphic resolution

Environment/lithology: marginal marine; conglomerate

• mixed shellbed fauna (lagoonal-estuarine, rocky shore, open sandy coast-shoreface), deposited in a high-energy bedload environment, probably as a longshore bar or spit, deposited during a rising sea-level after a glacial lowstand
• cross bedded pebble-shell conglomerate with whole and broken shells and coarse shell-grit in a coarse sand matrix, 4 m thick

Size class: macrofossils
