Macrofossils. The two Inoceramus species pacificus and australis are by far the most important and most widely distributed fossils and have been found at about 60 localities. Other macrofossils have been found at a few places only and appear to be restricted to a particular facies of shelf sediments. The type locality at Amuri Bluff is the most important. Mikonui Stream and Conway River mouth are only a few miles distant from Amuri Bluff. New macrofossil localities, with fossils similar to those at Amuri Bluff, have recently been discovered in the North Island near Lake Waikaremoana. The best is in the headwaters of Ruatahuna Stream, about 7 miles upstream from the Waikaremoana-Rotorua road. The following list has been compiled by Dr. C. A. Fleming from the species recorded from the “calcareous conglomerate” at Amuri Bluff and Mikonui Stream by Woods (1917), Wilckens (1922), and others. Collection GS13 represents all horizons from the Piripauan calcareous conglomerate to the Haumurian greensands, and species that are found in this collection only may be Haumurian in age and are marked with an asterisk (*). Species marked with a dagger (†) also occur in the Conway River railway cutting. Brachiopoda Discina sp.
