摘要
该文记述海南岛西部东方县鹅顶组和南龙组中的?类10属49种;研究表明,东方县昌化江西岸牛笛岭—江边村剖面鹅顶组的 Parafusulina qruperaensis-Parfusulina langdaiensis-Mesellina ovalis?类动物群属栖霞期中—中晚期Misellina claudiae顶峰时—Shenglla simplex延限时沉积;南龙组中上部的Parafusulina bosei-Parafusulina spp.?类动物群属茅口期早期 Cancellina-Neoschwagerina simplex时沉积;鹅顶组的Parafuslina gruperaensis-Parafusulina langdaiensis-Misellina ovalis?类动物群具有早二叠世栖霞期华夏-特提斯区的基本特征。
The fusulinids illustrated in this paper were collecte ? the Eding Formation consisting mostlyof carbonate rocks,and the Nanlong Formation consisin ? ly of clastic rocks in the west part of theHainan Island. The fauna contains 49 species assi? to 10 genera, namely, Parafusulina,Chalaroschwagerina, Pseudofusulina, Schwagerina, Eoparafu? na, Laxifusulina, Yangchienia, Schubertella,Minojapanella and Misellina. In the Niudiling--Jiangbiancun section at Dongfang ?n the west part of the Hainan Island, thefusulinids of the whole Eding Formation are called the Parafusulina gruperaensis--Parafusulinalangdaiensis--Misellina ovalis fusulinacean Fauna, including Parafusulina gruperaensis (Thompson etMiller), P. langdaiensis Yang, P. sapperi(Staff), P. granda (Nogami), P. splendens Dunbar et Skinner,P. australis Thompson et Miller, P. visseri Reichel, P. guatemalaensis Dunber, Chalaroschwagerina decoraSkinner et Wilde, C. bunongensis Li, Schwagerina callosa Han, Eoparafusulina subcylindrica (Deprat),Pseudofusulina wangmoensis Sheng, P. kueichowensis Sheng, P. houziguanica Sheng, Laxifusulinaneimonggolensis (Han), Minojapanella elongata Fujimoto et Kanuma, Schubertella phairayensis (Colani),Misellina ovalis, etc. This fauna belongs to the Misellina claudiae Chron--Shengella simplex Chron of themiddle--late Chihsian Age which coincides with the time range of Misellina. But,the fusulinids fromthe middle--upper part of the Nanlong Formation are named the Parafusulina bosei--Parafusulina spp.fauna,including Parafusulina bosei Dunbar et Skinner and Parafusulina spp. This fauna belongs to theCancellina--Neoschungerina simplex Chron of the early Maokouan Age which coincides with the timerange of Neoschwagerina. The Parafuanlina gruperaensis--Parafusulina langdaiensis--Misellina ovalis fusulinacean fauna containsMisellina but lacks Monodiexodina; it is identical with those from the Cathaysia---Tethyan Province ofthe Tethyan Realm during the Chihsian Age of the Early Permian(Sheng & Wang, 1981). Measurements of the fusulinids from the west port of Hainan Island are given in Table 1 in theChinese text.
