Chapman, F. 1918 Descriptions and revisions of the Cretaceous and Tertiary fish-remains of New Zealand. : . New Zealand Geological Survey paleontological bulletin 7 45 p.
Abstract: The majority of fishes herein described or referred to can be separated into their respective Cretaceous and Tertiary facies, but a smaller number is found bridging the expected gap between Cretaceous and Tertiary, which helps to show in some measure the existence of a passage series (the Cretaceo-Tertiary) with closely annectent elements in the fauna. This graduated series is found in the Amuri and Weka Pass sections to show, chiefly by the foraminifera, that there is no very definite break up to the Miocene stages. (auth)
