摘要

这里描述了从Tekeres(匈牙利南部,Mecsek Mts)的Tekeres Schlieren组的Tekeres Schlieren成员收集的中中新世(巴登纪)软骨鱼化石。软骨鱼类的组合异常多样且保存完好,包括全头类、塞拉基亚类和蝙蝠类。在巴德尼亚中部地区首次报道了9个分类群:Ischyodus sp.、Hexanchus cf.nakamurai、Centrophorus sp.、Isistius triangulus、Pristiophorus sp.、Sphyrna integra、Raja cf.gentili、Dasyatis cf.pastinaca和Mobula fragilis。动物群具有许多深水分类群的特征,是巴登尼亚中部旁系的第一个深海脊椎动物群。然而,典型的浅水、沿岸形式也存在,这些形式被磨损,经常被破坏,表明一些Tekeres动物群被从浅水、沿海环境转移并重新沉积到更深的水环境中。快速的盆地加深和由此产生的陡峭地形可能与潘诺尼亚盆地西南部持续的裂谷作用有关。大多数研究的软骨鱼动物群在地中海都有现存的代表,这支持了地中海和中央帕拉提斯之间通过斯洛文尼亚走廊的活跃动物联系,以及至少沿着这条通道存在的深水栖息地网络。

Chondrichthyan (Holocephali, Squalomorphii and Batomorphii) remains from the Badenian of southern Hungary (Tekeres, Mecsek Mountains): the first deepwater cartilaginous fishes from the Middle Miocene of the Central Paratethys
Middle Miocene (Badenian) chondrichthyan fossils collected from the Tekeres Schlieren Member of the Baden Formation at Tekeres (southern Hungary, Mecsek Mts) are described here. The chondrichthyan assemblage is exceptionally diverse and well‐preserved, and consists of holocephalans, selachians and batomorphs. Nine taxa are reported for the first time from the Badenian of the Central Paratethys: Ischyodus sp., Hexanchus cf. nakamurai, Centrophorus sp., Isistius triangulus, Pristiophorus sp., Sphyrna integra, Raja cf. gentili, Dasyatis cf. pastinaca and Mobula fragilis. The fauna is characterized by many deepwater taxa, making it the first bathyal vertebrate assemblage of the Badenian Central Paratethys. However, typically shallow water, littoral forms are also present, which are worn and often broken, indicating that some of the Tekeres fauna was transported and redeposited from a shallow, coastal setting into deeper water environments. Rapid basin deepening and the resulting steep topography can be linked to ongoing rifting of the south‐west Pannonian Basin. The majority of the studied chondrichthyan fauna have extant representatives in the Mediterranean, which supports an active faunal connection between the Mediterranean and the Central Paratethys via the Slovenian Corridor and the existence of a network of deepwater habitats at least along this pathway.

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.
