Where: New Zealand (45.2° S, 170.9° E: paleocoordinates 52.0° S, 172.5° W)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Ototara Formation, Rupelian (33.9 - 28.1 Ma)
• The Ototara Limestone ranges in age from Kaiatan to Early Whaingaroan (Edwards et al. 1991). The d18O values for brachiopods from Everett’s Quarry are the highest for any Lower Oligocene brachiopods and possibly correspond with either Antarctic glacial maxima Oi-1a or Oi-1b (Buening et al. 1998). This would place the Ototara Limestone at Everett’s Quarry in the C13n magnetic chronozone just after the Eocene/Oligocene boundary, with deposition occurring between 33.6 and 33 Ma (Buening et al. 1998).
• group of beds-level stratigraphic resolution
Environment/lithology: poorly lithified, shelly/skeletal limestone

Reposited in the USNM
