Corbies Creek群的长沟组包含了大量冈瓦纳中晚三叠世太平洋边缘低多样性海岸植被的遗迹。长沟植物岩整合覆于化石三角洲和海相拉底岩（开hikuan局部期）之上。发现了各种各样的果实化石，使人们更好地了解这些植物的植物学亲缘关系。被称为Todites maoricus sp. nov.的可育遗存表明了一种常见的蝶蕨叶的osmundale亲缘关系。Townrovia petasata gen. et sp. 11 .是可能的小孢子体和？紫菀属；种子蕨类植物叶片的大孢子叶可能属于厚皮蕨，在长沟以P. dubium (Burges) comb为代表。11 .和P. praecordillerae （Frenguelli）梳子。11 . volziacean针叶树的卵球果Telemachus lignosus sp. 11 .和“未识别的球果B”可能是另一种产叶的物种的果实。
Abstract The Long Gully Formation of the Corbies Creek Group contains abundant remains of the low-diversity coastal vegetation characteristic of the Middle and Late Triassic Pacific margins of Gondwana. The plant-bearing rocks in Long Gully conformably overlie fossiliferous deltaic and marine Ladinian rocks (Kaihikuan local stage). A variety of fossil fructifications were found, allowing better understanding of the botanical affinities of the plants. Fertile remains referred to Todites maoricus sp. nov., indicate osmundalean affinities for one common kind of sphenopterid fern frond. Townrovia petasata gen. et sp. nov. is the likely microsporophyll and ? Peltaspermum sp. indet. the likely megasporophyll of seed fern leaves referred to Pachydermophyllum, represented at Long Gully by P. dubium (Burges) comb. nov. and P. praecordillerae (Frenguelli) comb. nov. The ovulate voltziacean conifer cone Telemachus lignosus sp. nov. and “unidentified cone B” may be fructifications of a species also producing leaves r...
