“…As with the ammonoids, there are no records of Atractites in the early Aratauran of New Zealand, and it reappears with Metophioceras at North Marokopa (documented in this paper) and Arataura Point, Kawhia Harbour (Challinor 1996) at a level correlated with the Hettangian/Sinemurian boundary. Atractites also occurs at a comparable level in New Caledonia (Challinor & Grant-Mackie 1989).…”

Data on the changes in lithology and fauna across the Otapirian/Aratauran (Triassic/Jurassic) boundary are provided by 4 representative sections along the northern Marokopa coast. The latest Otapirian is characterised by a thick bed (40' m) of indurated sandstone, extensively bioturbated. Aratauran sediments consist of mudstone, siltstone and sandstone, with some intercalated tuffaceous beds. In the absence of ammonites, the transition from the bivalve Otapiria dissimilis (Otapirian) to O. marshalli (Aratauran) is used as faunal control points across the boundary. The first appearance of Otapiria marshalli also serves as a proxy for the Triassic/Jurassic boundary. At Marokopa, ammonite assemblages first appear some 15Á20 m above the boundary and the occurrence of Metophioceras is indicative of the base of the Conybeari Subzone (earliest Sinemurian). The hiatus in the ammonite record in New Zealand is a reflection of the worldwide biotic crisis across the Triassic/Jurassic boundary.

“…This alternative definition for the Temaikan allows the base of the stage to be located in the absence of the primary index species and therefore may be applicable to New Caledonian sequences where many of the lowest Temaikan faunas include Meleagrinella (see Challinor & Grant-Mackie 1989). In such sections, where the base of the stage is marked by the first appearance of Meleagrinella sp., the basal Temaikan beds are likely to be slightly to substantially younger than those in other sections, which contain Belemnopsis mackayi or B. deborahae.…”

“…Stevens (1965, p. 73) stated that B. mackayi has "the general form of a Bathonian-Bajocian Belemnopsis". Challinor & Grant-Mackie (1989) and Challinor (1991) regarded both B. mackayi and B. deborahae as being of Bajocian age. The firm correlation of Middle and earliest Late Temaikan, based on ammonites, with Retroceramus galoi was described from the Oxfordian of Indonesia (Boehm 1907), but in New Zealand Fleming & Kear (1960) dated its earliest occurrences in the Heterian stratotype as Kimmeridgian, based on Arkell's unpublished ammonite identifications.…”
