Two New Ordovician Trilobite Genera From Western Marginal Areas of the North China Platform
华北地台西缘两个奥陶纪三叶虫新属 In English
***************************************************************************************************
By Zhou Zhiyi
In connection with the preparation of a chapter of the monograph “Trilobite record of China” on the Ordovician trilobites, a large number of Chinese species were critically reviewed. Among others, two of them previously described from western marginal areas of the North China Platform respectively by Lu in Lu et al. (1976) as Bulbaspis ordosensis and by Zhou and Dean (1986) as Ischylophyma? zhiqiangi ought to be reassigned to new genera.

湖北宜昌奥陶纪大湾组的三叶虫新种Ovalocephalus eoprimitivus sp. Nov. In English
****************************************************************************************************************************
By Zhou Zhiyi
The trilobite genus Ovalocephalus Koroleva,1959 (=Hammatocnemis Kielan,1960) has long been considered to be biogeographically significant. It was endemic to peri-Gondwana and especially widely spread in China during the Ordovician (Lu and Zhou,1979; Zhou and Dean,1989). Its earliest species previously known is Ovalocephalus primitivus (Lu) with the holotype cranidium (Lu,1975,pl. 45,fig. 7) recorded from the upper Dawan Formation (early Darriwilian) of the Yichang area. Recently,some new material of the gen...

By Duan Ye
New polymerid trilobites are described from the middle part of the Huaqiao Formation in Fenghuang area, western Hunan, an area known as one of the most richly fossiliferous areas in China for Middle and Late Cambrian trilobite faunas.

New Material of Ordovician Trilobite Omeipsis Zhenxiongensis Luo, 1974
奥陶纪三叶虫Omeipsis zhenxiongensisLuo, 1974的新材料 In English
*****************************************************************************
By Luo zhuilin
Omeipsis is an endemic trilobite genus typical of the Ordovician Yangtze Block. It occurs only rarely in the Arenig of the Ordovician in association with inner shelf clastic facies. The genus was erected by Kobayashi (1951) on the basis of Acidaspis huangi Sun, 1931. Since then, only one more species, O. zhenxiongensis Luo, has further been referred to it.

Notes on the Genus Reedocalymene Kobayashi, 1951 (Trilobita, Ordovician)
论奥陶纪三叶虫属Reedocalymene Kobayashi, 1951 In English
*******************************************************************************
By Peng shanchi
For a long time, the concept of Reedocalymene has been unclear because its type species was erected on poorly preserved specimens. The abundant, well preserved material of Reedocalymene expansa Yi from the Miaopo Formation of the eastern Yangtze Gorges area in western Hubei, including the first recorded complete exoskeleton, reveals some dorsal and ventral morphologies that were little known previously in Reedocalymene . This material allows us to revise the genus comprehensively. Some of import...

Occurrence of Pseudoglyptagnostus (Cambrian Trilobita) in South Korea and the Significance of the Slope Biofacies of Korea
朝鲜南部的Pseudoglyptagnostus (三叶虫)并论朝鲜寒武纪斜坡相的意义 In English
********************************************************************************************************************************
By Zhang Wentang
Agnostus (Ptychagnostus?) orientalis Kobayashi, 1935 from the Olenoides Zone of the Machari Formation of South Korea, is a species of Agnostotes (Pseudoglyptagnostus) Lu, 1964, which is an agnostoid trilobite of medial Late Cambrian age rather than early Middle Cambrian. Kobayashi used the Olenoides to denominate a mixed zone of trilobites of Middle and Late Cambrian ages, and his 5 biozonations for the Machari Formation are incorrect. The occurrence of Coreolenus, Cheiruroides, Oryctocephal...

Arenig Trilobite Associations of Daping, Yichang, Hubei, South China
湖北宜昌大坪奥陶纪阿仑尼克期三叶虫生态组合 In English
***********************************************************************
By Samuel T. Turvey
Stratigraphical ranges of 30 trilobite species are recorded from the Ordovician Dawan Formation (Arenig) at Daping, Yichang, Hubei Province, China. Three trilobite associations are differentiated with respect to palaeobathymetrical and sedimentological gradients: the Asaphid Pseudocalymene Association, the Asaphid Raphiophorid Association and the Trinucleid Association. Stratigraphical occurrence of these associations within the formation reflects transgressive and regressive phases within the Arenig ...

The genus Palaeolenus Mansuy,estabished by Mansuy in 1912,includes three species:P.douvillei Mansuy,P.lantenoisi Mansuy,and P.deprati Mansuy.In 1966,Chang(1966) renamed the third one—? alaeolenus deprati Mansay——under the genus Megapalaeolenus Chang.Howerver,it was quite recently that Lin and Peng(2004) contradicted its validity,for they considered its type species to be synonyrnous with P.douvillei,and referred Megapalaeolenus to the Upper Canglanpuan Palaeolenus instead.
