Quantitative palaeoclimate estimates from Late Cretaceous and Paleocene leaf £oras in the northwest of the South Island, New Zealand
Three new plant macrofossil assemblages were collected from Late Cretaceous and Paleocene fluvio-lacustrine sediments of the Pakawau and Kapuni groups in the northwest of the South Island, New Zealand. Palaeoenvironmental interpretations were made from each locality and palaeoclimate was deduced fro...
