Also known as I40/f30
Where: North Otago, New Zealand (44.8° S, 170.5° E: paleocoordinates 50.6° S, 176.3° W)
• coordinate stated in text
When: Miller Member (Otekaike Limestone Formation), Waitakian (25.2 - 21.7 Ma)
• Graham et al.  gave strontium dates for the Trig Z sequence (derived from analysis of foraminifera and macrofossils, mainly pectinids), including 23.6 to 24.2 Ma for the upper part of the Miller Member (I40/f305; 87Sr/86Sr values include 0.708263+/2 0.000011), and 23.3 to 23.9 Ma for the base of the G. woodi zone (I40/f304; 87Sr/86Sr =0.708258+/20.000011). The age for Otekaikea marplesi is taken here as $23.9 Ma.
•The type- locality lies at or near the right side of Gage’s (: Fig. 25) photograph of the type locality of the Waitakian Stage. The locality has been prospected, but no other significant material of O. marplesi has been found.
•Was given as Chattian.
