“…The widespread T. arctica, T. crassinervis, T. vittata and an endemic species T. thomsoniana are also present in New Zealand (Arber 1917), but it is not clear whether these were also pentoxylaleans since similar leaves were also produced by some cycads, bennettites and ferns. Taeniopteris is a very simple leaf morphogenus, leaving little to distinguish the species other than a range of dimensions, the approach used by Blaschke & Grant-Mackie (1976) for delimiting Taeniopteris species at Port Waikato and the Clent Hills. A study of large collections would give a clearer idea of the species limits and could well reduce the number of taxa recognised from New Zealand.…”

New Zealand's Jurassic plant fossils are known from non-marine settings in two terranes: the Murihiku forearc basin and from a small area on the Rakaia Terrane, an accretionary prism. These terranes lay in relatively high latitudes along the Gondwana margin but their precise location, latitude and position with respect to each other is unclear. The flora was dominated by conifers, ferns, bennettitaleans, pentoxylaleans and locally equisetaleans, but it is relatively depauperate, perhaps reflecting a high latitude position. Most climate indicators suggest a warm temperate climate with rainfall that was not especially high and that might have been seasonal at times. Revision of the New Zealand Jurassic flora is overdue, and while new genera may be discovered, species numbers may well decrease.

“…Comparison: Of the two populations of taeniopterid foliage examined by Blaschke and Grant-Mackie (1976), from Waikato Heads and Clent Hills, the Marybank specimens compare closely with the latter, already distinguished as T. thomsoniana by Arber (1917). It is likely that the Waikawa material separated by Arber as T. vittata contains specimens similar to those from Marybank, but this population would require reexamination to determine this point.…”

The Drumduan Group, consisting of the Marybank and Botanical Hill formations, forms a fault-bounded block northeast of Nelson City, and comprises bedded pyroclastic and epiclastic (including sedimentary) debris of probable terrestrial deposition. Lawsonite is widespread, but not uniformly present. Plant macrofossils, including Mataia podocarpoides, Rissikia talbragarensis, Taenioptens thamsor/lana, T sp. cf. T crassinervis, Cladophlebis sp. and Podozamites sp., in the Marybank Formation indicate aJ urassic age. The group is separated from the Brook Street Volcanics (Permian) by the Delaware Fault Zone, along which arc slivers of Wakapuaka Phyllonite (pumpellyite-actinolite facies). In the west the group shows widespread hydrothermal alteration related to the adjacent Tasman Intrusives, but the Brook Street rocks arc not similarly altered and are not metamorphosed beyond prehnite-pumpellyite facies. We infer that during the Rangitata Orogeny the Drumduan Group, the Tasman Intrusives, and the underlying basement rocks, including the Pepin Group, were underthrust below the Brook Street Volcanics along the Delaware Fault Zone. The resulting depth of burial and confining nature of the overthrust plate on one side, and the Tasman Intrusives on the other, were responsible for the development of metamorphic rocks characterised by a relatively high PIT ratio and by the crystallisation oflawsonite, locally in abundance. Fluid pressures were probably nowhere greater than lithostatic pressure. The Delaware Fault Zone appears to form a major suture between the rocks of cast and west Nelson. The Drumduan Group, the Tasman Intrusives, and the Pepin Group arc assigned to the Tuhua Orogen.

Pre-Cretaceous basement in the Mt Somers area consists of Torlesse Supergroup rocks ofprehnite-pumpellyite facies which are here subdivided into the Mt Taylor Group (Middle-Late Triassic; new group), the Clent Hills Group (Middle-Late Jurassic; amended group), and undifferentiated Torlesse Supergroup. Mt Taylor Group is further subdivided into three new formations: (a) Fingers Formation (Kaihikuan-?Oretian (Ladinian-?Carnian) of late Middle to perhaps early Late Triassic age) of medium-coarse-grained sandstone and minor interbedded alternating sandstone-siltstone sequences containing the key fossils Daonella sp., Praegonia sp., and Spiriferina cf. abichi Oppel. Part of this formation consists of distinctive massive, white, micaceous, coarse-grained feldsarenite with dark calcareous spheroidal concretions. (b) Pudding Hill Formation (Middleearly Late Triassic) a flysch-like sequence of alternating dark grey, fine sandstone and siltstone turbidites, and contains the tube fossil Torlessia mackayi Bather. This formation appears to interdigitate with the Fingers Formation. (c) Balmacaan Formation (Kaihikuan (Ladinian), late Middle Triassic), a fine-to mediumgrained sandstone and siltstone sequence containing conglomerate beds. The key fossil of this formation is Agonisca corbiensis Fleming. Balmacaan Formation appears to be a near-shore (proximal) deposit, Fingers Formation an intermediate reworked deposit, and Pudding Hill Formation a distal turbidite deposit of a continental shelf submarine fan. A west to east palaeoslope is suggested. Undifferentiated Torlesse rocks, of probable Triassic age, occur in the area. These unfossiliferous rocks are lithologically similar to the Mt Taylor Group and in particular to the Balmacaan Formation but in places grade into a phyllite or cataclasite, apparently related to faulting. The Clent Hills Group contains both non-marine and marine s~quences with probable gradations between the two. A late Jurassic (Puaroan) age is indicated by the presence of Inoceramus cf. gracilis Holdhaus and Buchia sp. indet., but other marine fossil assemblages indicate a possible range of Middle-Late Jurassic (Temaikan-Puaroan). Conglomerate channel deposits containing tree trunks, and siltstone beds containing well preserved plant remains are a conspicuous feature of the formation. The Clent Hills Group is interpreted as a deltaic sequence.
