Where: New Zealand (38.4° S, 177.3° E: paleocoordinates 80.3° S, 177.5° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Koranga Sandstone Formation, Late/Upper Aptian (122.5 - 113.0 Ma)
• STRATIGRAPHIC RELATIONS: From Koranga Sandstone of the Taitai Series, overlies Torelsse supergroup along Maccoyella Ridge and is unconformably overlain by the the Te Wera Sandstone. THICKNESS: From bed within formation that varies in thickness between 116 (at this area) and 76 m (locally).
