The paper describes new Lower Jurassic corals from the South-Eastern Pamir Mountains (Tajikistan) and interprets their relationships with contemporaneous West Tethyan corals. Taxonomic similarities with Pliensbachian European and North African faunas indicate a Pliensbachian age for this fauna, which was previously considered to be of Hettangian/Sinemurian age. Together with the taxa earlier described from the Pamirs, this fauna consists of 30 species of 25 genera, including Triassic holdover genera such as Stylophyllopsis, Phacelostylophyllum and Eocomoseris. The bulk of the fauna represents new Jurassic genera: Alichurastrea, Eomicrophyllia, Guembelastreomorpha, Gurumdynia, Pinacomorpha, Protostephanastrea, Psenophyllia, Sedekastrea and Stylimorpha. Earlier coral studies of the region concerned the genera: Archaeosmilia Melnikova, 1975, Archaeosmiliopsis Melnikova, 1975, Cylismilia Roniewicz, 1988, Pachysmilia Melnikova, 1989, and Prodonacosmilia Melnikova in Melnikova and Roniewicz, 1976. Two species that were considered to belong to the genus Cylismilia, are redescribed and reclassified in the genera Psenophyllia, and Archaeosmilia Melnikova, respectively.

来自中亚帕米尔山脉的下侏罗纪珊瑚

该论文描述了来自东南帕米尔山脉(塔吉克斯坦)的新下侏罗纪珊瑚,并解释了它们与同期西特提斯珊瑚的关系。与 Pliensbachian 欧洲和北非动物群的分类学相似性表明该动物群属于 Pliensbachian 时代,以前被认为是 Hettangian/Sinemurian 时代。连同早先从帕米尔高原描述的分类群,该动物群由 25 个属的 30 种组成,包括三叠纪的保留属,如柱状属、PhacelostylophyllumEocomoseris。大部分动物代表新的侏罗纪属:AlichurastreaEomicrophylliaGuembelastreomorphaGurumdyniaPinacomorphaProtostephanastreaPsenophylliaSedekastreaStylimorpha。该地区早期的珊瑚研究涉及以下属:Archaeosmilia Melnikova,1975,Archaeosmiliopsis Melnikova,1975,Cylismilia Roniewicz,1988,Pachysmilia Melnikova,1989,以及Melnikova 和 Roniewicz 的Prodonacosmilia Melnikova,被认为属于 19 个物种。Cylismilia,在PsenophylliaArchaeosmilia中重新描述和重新分类 梅尔尼科娃分别。
