Also known as GS 12137
Where: Chatham Islands, New Zealand (44.3° S, 176.8° E: paleocoordinates 54.5° S, 155.4° W)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Matanginui Limestone Member (Te Whanga Limestone Formation), Waipawan (55.8 - 53.0 Ma)
• THICKNESS: Matanginui Limestone is approximately 25 m thick at the type section. STRATIGRAPHIC RELATIONS: Matanginui Limestone is the lower member of the Te Whanga Limestone and conformably overlies the Red Bluff Tuff, and is unconformably overlain by younger strata. AGE: It is assigned an Waipawan-Bortonian local stage=Thanetian-Bartonian age based on biostratigraphy from combination of faunal groups. The particular collection is dated as Late Waipawan=Ypresian.
