本文描述陕西镇安西口石门垭下石炭统顶部及中石炭统底部的四射珊瑚9属11新种。 1982年6月笔者随同中国地质科学院“石炭二叠系界线”专题研究队丁蕴杰等在陕西南部镇安县西口区石门垭测制剖面。该剖面中所采早、中石炭世四射珊瑚交由笔者鉴定。本文即为这批材料中的新属种,共9属(包括3新属、2新亚属)11新种。石门垭剖面中、下石炭统为连续沉积,岩性均为灰、浅灰色厚层灰岩。此界线上下发现有四个主要珊瑚化石层,自上而下产: 4.Acrocyathus xikouensis sp.nov.,Amandophyllum xikouense sp.nov.,Carruther-sella(Liuzhouia) shimenyaensis subgen.et sp.nov.,Koninckocarinia shaanxiensis sp.nov。,Kionophyllum sp.,Amygdalophylloides sp.和 pseudostaffella。 3.Liuia typica gen.et sp.nov.和pseudostaffella。 2.Semenoffia (pseudosemenoffia) typica subgen. et sp.nov.,Carruthersellazhenanensis sp.nov.。 1.paranemistium typicum gen.et sp.nov.,Cystilophophylloides typicus gen.et sp.nov.,C.shimenyaensis gen。et sp.nov.,C.xikouensis gen.et sp.nov,Arachnolasmaspp.,Amplexocarinia sp.,Zaphrentoides sp.,Siphonodendron sp.,Protocarcinophyllum sp. 上列层3-4内产蜓仅pseudostaffella,故时代为中石炭世早期pseudostaffella带。层1产产大量Arachnolasma种群及Protocarcinophyllum其时代定为早石炭世晚期似无疑问。层2中未采得蜓类,其时代据四射珊瑚Carruthersella的存在暂定为早石炭世末期。丁蕴杰同志给予笔者研究这批材料的机会并与夏国英、赵松银等同志共同采集化石,欧阳萱、金同安等同志给予笔者支持和帮助均此致谢。
This article describes 11 new species of 9 genera of coral in the Lower Carboniferous of Shimenaya and the bottom of Carboniferous in the west of Zhen’an, Shaanxi Province. In 1982 June with the Chinese Academy of Geological Sciences, “Permian Boundary Line” project team Ding Yunjie et al in Shaanxi Province Zhen’an County West exit of Shek Mun Ya profile section. The early and Middle Carboniferous coral collected in the profile was identified by the author. This article is the new species of these materials, a total of 9 genera (including 3 new genera, 2 new subgenus) 11 new species. In the section of Shimenghuya, the Lower Carboniferous is continuously deposited with lithic gray and light gray thick limestone. There are four major coral fossil layers up and down this line, from top to bottom: 4.Acrocyathus xikouensis sp.nov., Amandophyllum xikouense sp.nov., Carruther-sella (Liuzhouia) shimenyaensis subgen.et sp.nov., Koninckocarinia shaanxiensis sp.nov. , Kionophyllum sp., Amygdalophylloides sp. And pseudostaffella. 3.Liuia typica gen.et sp.nov. And pseudostaffella. 2.Semenoffia (pseudosemenoffia) typica subgen. Et sp.nov., Carruthersellazhenanensis sp.nov. 1.paranemistium typicum gen.et sp. Nov., Cystilophophylloides typicus gen. Et sp. Nov., C. shimenyaensis gen. et sp.nov., C. xikouensis gen.et sp. nov, Arachnolasmaspp., Amplexocarinia sp., Zaphrentoides sp., Siphonodendron sp., Protocarcinophyllum sp. Early Carboniferous pseudostaffella band. There is no question that the large number of Arachnolasma populations and Protocarcinophyllum producing in layer 1 were dated to the late Carboniferous stage. Layer 2 was not obtained in the category of the dragonfly, its era according to the existence of the coral Carruthersella tentatively set for the late Carboniferous. Comrade Ding Yunjie gave the author the opportunity to study these materials and collected the fossils together with Xia Guoying and Zhao Songyin and other comrades, and thanks comrades Ouyang Xuan and Jin Tongan for their support and help.
