“…Assigning late Otamitan and Warepan faunas an Upper Norian age carries the implication of a possible Norian age for all of the Otamitan Stage and perhaps some or all of the Oretian Stage (Table 1). Certainly, the simple correlation of Oretian and Otamitan with Carnian and Warepan with Norian stages cannot be sustained (d. (Jenkins and Jenkins 1971). Heterastridium has not been found in the limestones.…”

“…More forms have been added during my own fieldwork. In addition, Jenkins & Jenkins (1971) have reported two W arepan micro faunas consisting of fish scales and teeth, four genera of Foraminiferida, and 12-15 conodont species, and Strong (1984) has given a preliminary report of Warepan foraminiferal faunas from the North Island.…”

“…Reference needs to be made here to Jenkins & Jenkins's (1971) record of "early" or "lower" and "late" or "upper" Norian conodont faunas in two Monotis-bearing limestones in Canterbury. The authors pointed out that these divisions constitute an informal bipartite division of the Norian Stage, not to be confused with the tripartite division used by other authors (Silberling & Tozer 1968;Gromov & Tuchkov 1971;Westermann 1973b;Tozer 1979).…”

The Warepan Stage of the Upper Triassic: Redefinition and subdivision

Recently published studies show that the current definition of the Warepan Stage of the New Zealand-New Caledonian Upper Triassic, based upon the incoming of Monotis (Entomonotis) richmondiana Zittel, is inadequate. Past practice has relied upon the first appearance of the genus Monotis, and earliest species are not M. richmondiana but members of the subgenus Eomonotis. To avoid the stage boundary being placed within, instead of at the base of, a sequence of short-lived rapidly evolving species of the one genus, it is recommended that M. richmondiana be replaced as the Warepan index fossil by the earliest species in the region, namely, Manolis (Eomonotis) kiritehereensis G-M., M. (E.) rauparaha mokaui G-M., and M. (E.) murihikuensis taringatura G-M. Stratigraphic analysis of New Zealand sequences containing these three taxa indicates that they are likely to have been contemporaries. This redefinition calls into doubt the suitability of the Rocky Dome (South Otago) area as a stratotype, for Eomonotis has not been recorded here. Rather than take the more drastic step of selecting a new stratotype and designating a new name for the stage, the familiar name is retained and the Kiritehere coastal section, southwest Auckland, is named as a reference section to demonstrate more fully the faunal succession.Taxonomic re-evaluation of New Zealand Manotis provides the opportunity for further formal subdivision. Two substages are proposed, the Lower Warepan Kiriteherean Substage based on the rangezone of Eomonotis in New Zealand, and the Middle Warepan Marokopan Substage based on the rangezone of Entomonotis. A potential Upper Warepan substage is left undefined pending fuller description of the Warepan fauna.

“…Triassic conodonts have been known from the South Island since the work of Jenkins (1968) and Jenkins & Jenkins (1971). Subsequently, Simes (1985) and Marden et al (1987) have reported Triassic conodont faunas from the North Island.…”

New information on the age and thermal history of a probable Early Triassic siltstone near Kaka Point, South Island, New Zealand

The conodont Neospathodus homeri s.l. supports a late Early Triassic, Malakovian, age for an ammonoidrich horizon in the Potiki Siltstone, 0.9 km south of Kaka Point, southeast Otago, rather than an alternative designation of Early to Middle Anisian. The conodont colour alteration index suggests a thermal history with temperature not exceeding c. 80°C. The Kaka Point structural belt appears to have had a tectonic and thermal history different from that of the adjacent Murihiku Terrane.
