摘要

二叠纪-三叠纪灭绝后,安尼期(中三叠世)见证了腕足动物的多样化。中国西北祁连山南段的安尼西亚腕足动物群在物种水平上是世界上同类动物群中分类多样性最高的。然而,这个偏远地区的许多分类群仍然定义不清,因此需要修订。本文对祁连山南部天军地区安尼期大家连组和齐尔马沟组保存完好的碳酸盐和硅化标本进行了分类,包括15个腕足类属23种(包括2个不确定种)。2新属(Crenulatomargus, tianjunnospina)和6新种(Costirhynchopsis xuui, Crenulatomargus terebratulformis, Schwagerispira elegans, Lepismatina?建立了inusitata, tianjunnospina junheensis, qiilianoconcha circularis)。修订了三角鼻虫、阳孔虫、Sinucostella、Aequspiriferina、qiilianoconcha、Parantiptychia的诊断。此外,原翅虫属和三翅虫科分别被认为是七翅虫科和四翅虫科的初级近义词。经系统描述和分类校正,祁连南部腕足动物区系已确定26属56种(含7种不确定种)。对全球14个腕足动物群的网络分析表明,在安尼期发现了6个类群(青岩、祁连南部-西秦岭、喜马拉雅-北西伯利亚、青海中部、新西兰和欧洲/特提斯西部)。与来自特提斯西部的动物相比,特提斯东部的动物之间的联系较少。除了邻近的西秦岭地区外,其他同时期动物群与祁连动物群的亲缘性都要低得多。

The Anisian (Middle Triassic) brachiopods from the southern Qilian Mountains, north‐western China
The Anisian (Middle Triassic) witnessed the diversification of brachiopods after the Permian–Triassic extinction. The Anisian brachiopod fauna from the southern Qilian Mountains in north‐western China has the highest taxonomic diversity at species level among coeval faunas worldwide. Nevertheless, many taxa from this remote region remain poorly defined, and therefore require emendation. Here we describe 23 species (including two uncertain species) in 15 brachiopod genera based on well‐preserved carbonate and silicified specimens collected from the Anisian Dajialian and Qieermagou formations in Tianjun, southern Qilian Mountains. Two new genera (Crenulatomargus, Tianjunospina) and six new species (Costirhynchopsis xui, Crenulatomargus terebratuliformis, Schwagerispira elegans, Lepismatina? inusitata, Tianjunospina junheensis, Qilianoconcha circularis) are erected. The diagnoses of Triasorhynchia, Yangkongia, Sinucostella, Aequspiriferina, Qilianoconcha and Parantiptychia are emended. Also, the genus Eoantiptychia and the family Triasorhynchiidae are regarded as junior synonyms of Qilianoconcha and Tetrarhynchiidae, respectively. After systematic description and taxonomic emendation, 56 species (including seven uncertain species) in 26 genera are confirmed in the southern Qilian brachiopod fauna. Network analysis of 14 brachiopod faunas worldwide shows that six groups were detected during the Anisian (Qingyan, southern Qilian – western Qinling, Himalaya – northern Siberia, central Qinghai, New Zealand, and Europe/western Tethys). Compared with those from the western Tethys, the eastern Tethyan faunas are less allied to each other. Except for the assemblage from the adjacent western Qinling area, other coeval faunas have much lower affinities with the Qilian fauna.

期刊介绍: Papers in Palaeontology is the successor to Special Papers in Palaeontology and a journal of the Palaeontological Association (www.palass.org). The journal is devoted to the publication of papers that document the diversity of past life and its distribution in time and space. Papers in Palaeontology is devoted to the publication of papers that document the diversity of past life and its distribution in time and space. As a sister publication to Palaeontology its focus is on descriptive research, including the descriptions of new taxa, systematic revisions of higher taxa, detailed biostratigraphical and biogeographical documentation, and descriptions of floras and faunas from specific localities or regions. Most contributions are expected to be less than 30 pp long but longer contributions will be considered if the material merits it, including single topic parts. The journal publishes a wide variety of papers on palaeontological topics covering: palaeozoology, palaeobotany, systematic studies, palaeoecology, micropalaeontology, palaeobiogeography, functional morphology, stratigraphy, taxonomy, taphonomy, palaeoenvironmental reconstruction, palaeoclimate analysis, biomineralization studies.
