The Late Jurassic-Early Cretaceous (164-100 Ma) represents one of the main transitional periods in life history. Recent studies unveiled a complex scenario in which abiotic and biotic factors and drivers on regional and global scales due to the fragmentation of Pangaea resulted in dramatic faunal and ecological turnovers in terrestrial and marine environments. However, chondrichthyan faunas from this interval have received surprisingly little recognition. The presence of numerous entire skeletons of chondrichthyans preserved in several localities in southern Germany, often referred to as Konservat-Lagerstätten (e.g., Nusplingen and the Solnhofen Archipelago), provides a unique opportunity of to study the taxonomic composition of these assemblages, their ecological distributions and adaptations, and evolutionary histories in detail. However, even after 160 years of study, the current knowledge of southern Germany's Late Jurassic chondrichthyan diversity remains incomplete. Over the last 20 years, the systematic study and bulk sampling of southern Germany's Late Jurassic deposits significantly increased the number of known fossil chondrichthyan genera from the region (32 in the present study). In the present work, the fossil record, and the taxonomic composition of Late Jurassic chondrichthyans from southern Germany are reviewed and compared with several contemporaneous assemblages from other sites in Europe. Our results suggest, , that the Late Jurassic chondrichthyans displayed extended distributions within Europe. However, it nevertheless also is evident that the taxonomy of Late Jurassic chondrichthyans is in urgent need of revision.
晚侏罗世-早白垩世（1.64亿至1.00亿年前）是生命史上主要的过渡时期之一。最近的研究揭示了一个复杂的情景，即由于泛大陆的分裂，区域和全球尺度上的非生物和生物因素及驱动因素导致陆地和海洋环境中动物群和生态发生了巨大变化。然而，这一时期的软骨鱼类群却出人意料地未得到多少关注。在德国南部的几个地方保存着许多完整的软骨鱼类骨骼，这些地方常被称为化石库（如努斯普林根和索伦霍芬群岛），这为详细研究这些组合的分类组成、生态分布与适应以及进化历史提供了独特的机会。然而，即使经过160年的研究，目前对德国南部晚侏罗世软骨鱼类多样性的了解仍然不完整。在过去20年里，对德国南部晚侏罗世沉积物的系统研究和大规模采样显著增加了该地区已知化石软骨鱼类属的数量（本研究中有32个）。在本研究中，我们回顾了德国南部晚侏罗世软骨鱼类的化石记录和分类组成，并与欧洲其他地点的几个同期组合进行了比较。我们的结果表明，晚侏罗世软骨鱼类在欧洲范围内分布广泛。然而，同样明显的是，晚侏罗世软骨鱼类的分类学迫切需要修订。
