摘要

描述了德国西北部Hambach露天褐煤矿中中新世河道充填物中的齿状物质。Hambach 6C区系多样性较高，包括Glirudinus undosus、Muscardinus thaleri、Muscardinus sansaniensis、Miodyromys aegercii、Paraglirulus werenfelsi、Microdyromys koenigswaldi和Paraglis astaracensis 6属7种，是中中新世欧洲地区的典型类群。Hambach 6C在区系组成和多样性方面与德国南部mn5地区Schönenberg最接近，但也与中中新世晚期的动物群有许多共同的类群。Hambach 6C地区的滑鱼物种丰富度和其他脊椎动物遗骸表明，中中新世气候最适期(MCO)是一个温暖湿润的森林环境。

Dormice (Rodentia, Gliridae) from the Middle Miocene of Hambach 6C, Northwest Germany

Glirid dental material is described from the Middle Miocene channel fill of the Hambach open-cast lignite mine in northwestern Germany. The fauna Hambach 6C shows a high diversity with seven species in six genera: Glirudinus undosus, Muscardinus thaleri, Muscardinus sansaniensis, Miodyromys aegercii, Paraglirulus werenfelsi, Microdyromys koenigswaldi, and Paraglis astaracensis, which are characteristic taxa in Middle Miocene European localities. Regarding the faunal composition and high diversity, the Hambach 6C assemblage is closest to that of the MN 5 locality Schönenberg in southern Germany, but also shares many taxa with late Middle Miocene faunas. The species richness of glirids, combined with other vertebrate remains in Hambach 6C indicates a warm, humid forested environment during the Mid-Miocene Climate Optimum (MCO).

期刊介绍： Geobios publishes bimonthly in English original peer-reviewed articles of international interest in any area of paleontology, paleobiology, paleoecology, paleobiogeography, (bio)stratigraphy and biogeochemistry. All taxonomic groups are treated, including microfossils, invertebrates, plants, vertebrates and ichnofossils. Geobios welcomes descriptive papers based on original material (e.g. large Systematic Paleontology works), as well as more analytically and/or methodologically oriented papers, provided they offer strong and significant biochronological/biostratigraphical, paleobiogeographical, paleobiological and/or phylogenetic new insights and perspectices. A high priority level is given to synchronic and/or diachronic studies based on multi- or inter-disciplinary approaches mixing various fields of Earth and Life Sciences. Works based on extant data are also considered, provided they offer significant insights into geological-time studies.
