Stratigraphic framework and time slices
Reconnaissance sandstone geochemistry, provenance, and tectonic setting of the lower Paleozoic terranes of the West Coast and Nelson, New Zealand
Abstract Broad chemical characteristics of sedimentary rocks from the Buller and Takaka Terranes have been examined, and provenance and tectonic setting inferred, using whole‐rock major and trace…

Estimating the Rock Volume Bias in Paleobiodiversity Studies
TLDR
Data from New Zealand indicate that outcrop area is likely to be a reliable proxy of rock volume in both stable cratonic regions, where the paleobiodiversity record is strongly correlated with relative sea level, and on tectonically active margins.

The Oligocene bottleneck and New Zealand biota: genetic record of a past environmental crisis
TLDR
The data support the existence of a widespread genetic bottleneck during the mid-Cenozoic in New Zealand and demonstrate the benefits of synthesizing traditional research with new molecular techniques.

High-resolution, early Paleozoic (Ordovician-Silurian) time scales
For much of the geologic time scale, resolving power appears to be limited by the duration of biostratigraphic zones and subzones. Yet these zones exploit the appearance and disappearance events of…
