广西隆林地区早石炭世异珊瑚类
LOWER CARBONIFEROUS HETEROCORALLIA OF LONGLIN AREA,GUANGXI
【摘要】 本文描述异珊瑚类3属9种,标本采自广西隆林、隆或等地,其层位相当于贵州下石炭统大塘阶上部的Yuanophyllum带。建立新属一个Longlinophyllia(gen.nov.),新种和新亚种6个: Hexaphyllia longliensis (sp. nov.), H. gigantea crassotheca (subsp. nov.), H. tenuis longhuoensis (Subsp. nov.), Heterophyllia kitakamiensis flexuosa (subsp. nov.), H. guangxtensis (sp.nov.) 和 Longlinophyllia ditabulata (gen. et sp. nov.)。新属Longlinophyllia的隔壁和横板均可分为轴部与侧部两种类型,不同于Heterophylliidae科内的属,因此可以建立一个新科Longlinophylliidae(fam. nov.)。
【Abstract】 The Heterocorallia described in this paper were collected in 1981 from the upper Datang Stage of Lower Carboniferous of Longlin area, Guangxi. The authors described 3 genera and 9 species, including 1 new genus and 6 new species and subspecies, and established a new family. They are Hexaphyllia lyelli (Duncan), H. mirabilis (Duncan), H. cf. transversa Yu et al., H. gigantea crasotheca (subsp. nov.), H. tenuis longhuoensis (subsp. nov.), Heterophyllia kitakamiensis flexuosa (subsp. nov.), H. guangxiensis (sp. nov.), Longlinophyllia ditabulata (gen. et sp. nov.).The new family is similar to Heterophylliidae in some characters. The main differences between them are that the septa and tabullae of the new family may be clearly subdivided into two kinds, the axial and the peripheral. The genus Heterophyllia was subdivided into two subgenera by O. H. Schindewolf in 1941, i.e.H. (Heterophyllia)and H. (Heterophylloides). They differ only in the number of septa. We consider that they are congeneric and Heterophylloides is a synonym of Heterophyllia.The contact relation of the Lower Carboniferous and the Devonian in Longlin area is disconformable. The thickness of the Lower Carboniferous is about 300 m. The heterocorals occur in the upper part of the strata. It may be pointed out that this coral bearing horizon may be correlated with the Yuanophyllum Zone of C. C. Yu and with the brachiopod Assemblege of Gigantoproductus edelburgensis-Striatifera angusta-Gondolina weiningensis of S. P. Yang, which occur widely in South China.
