Abstract
A new thin‐section study of limestones from Wherowhero Point, Orua Bay, Northland, has produced a fauna of 24 fusuline taxa and 19 smaller foraminifers. The fusulines are much more diverse than earlier records have shown and include genera and species not previously recorded (e.g., Pseudokahlerina compressa Sosnina, Reichelina cf. lamarensis Skinner & Wilde, Rauserella cf. breviscula Sosnina, Chusenella urulungensis Wang et al., Yabeina ampla Skinner & Wilde, Dunbarula, and Pseudo‐fusulina). A species previously recorded as Yabeina parvula Skinner & Wilde is re‐identified as Y. globosa (Yabe), and that identified earlier as Lepidolina multiseptata (Deprat) is determined to be its evolutionary precursor L. shiraiwensis Ozawa. The latter species, together with Kahlerina pachytheca Kochansky‐Devide & Ramovs, Neoschwagerina margaritae Deprat, and Yabeina archaica Dutkevich, are the most widespread species in the eight collections studied from four localities, and these four species and Yabeina ampla are the most abundantly represented. The fauna clearly belongs to the Yabeina‐Lepidolina fusulinid zone, and to the Late Permian Midian Stage, and the presence of Neoschwagerina margaritae and Yabeina archaica indicates that some samples are probably Early Midian. A Midian age is also supported by the smaller foraminifers Frondina permica Civrieux & Sessauvagie, Robuloides cf. lens Reichel, Dagmarita, Hemigordiopsis, and Neoendothyra. Paleogeographic relationships lie with eastern Asia and less strongly also with western North America.
