Geography
Country: | New Zealand | State/province: | North Otago |
Coordinates: | 44.8° South, 170.5° East (view map) | ||
Paleocoordinates: | 50.6° South, 176.3° West | ||
Basis of coordinate: | stated in text |
Time
Key time interval: | Waitakian |
Age range of interval: | 25.20000 - 21.70000 m.y. ago |
Stratigraphy
Formation: | Otekaike Limestone | Member: | Miller | ||
Stratigraphy comments: Graham et al. [24] 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 ([22]: 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. |
