Hornibrook, N. de B. 1961 Tertiary Foraminfera from Oamaru district (NZ). Part 1, Systematics and distribution. Wellington: New Zealand Geological Survey. New Zealand Geological Survey paleontological bulletin 34(1). 192 p.
Abstract:
The distribution of 500 species of Foraminifera in 60 samples from the marine Tertiary rocks of Oamaru district (Danian-Paleocene, Middle Eocene through to Lower Miocene) is recorded; 391 species are dealt with in the systematic section and 300 are illustrated, many being from the late H.J. Finlay's holotypes. A new subfamily, Notorotaliinae, is proposed for the family Elphidiidae. 100 new species are described and the following new genera are proposed: Semirosalina and Nummodiscorbis (family Discorbiidae); Cribrorotalia and Discorotalia (family Elphidiidae). The status of the following systematic groups is discussed fully: genus Bolivinopsis , Discorbis and related genera, Stomatorbina and Mississippina , subfamily Discorbinellinae, family Elphidiidae and the genus Notorotalia . Notes are provided on the distribution of most of the species in the Tertiary of New Zealand and on their vertical ranges. (auth)
