The small, Lower Cretaceous, iron ore deposit at Zengővárkony (Mecsek Mountains, southern Hungary, Europe) contains new brachiopod taxa of kingenoid relationships. Dictyothyropsis vogli, Zittelina hofmanni, and Smirnovina ferraria are described as new species from late Valanginian to earliest Hauterivian strata. The new taxa strengthen the presence of Early Cretaceous biogeographical connections with the Western Carpathians and the Pieniny Klippen Belt of southern Poland. The newly described taxa have significantly larger dimensions than their closest relatives from the type localities, which is in line with previous research on brachiopods from this environment. These brachiopods lived in a nutrient-rich, unique environment related to iron-ore deposition linked to former hydrothermal activity on the seafloor that might have contributed to the large size of these brachiopods. Larger than normal rhynchonellide and terebratulidine brachiopods have previously been recorded from this locality.UUID: http://zoobank.org/353882-2838-4eb7-b21a-8cc665d13408

Zengővárkony早白垩世(匈牙利梅切克山脉)发现的体型较大的新型金刚体(Terebratellidina)腕足类动物

Zengővárkony(匈牙利南部,欧洲的梅切克山脉)的下白垩统小型铁矿床包含新的腕足类动物类群。盘螟,齐特利娜霍夫曼尼, 和Smirnovina ferraria被描述为从瓦朗宁晚期到最早的豪特里夫地层的新物种。新的分类群加强了早白垩世与西喀尔巴阡山脉和波兰南部皮尼尼克里彭带的生物地理联系。新描述的分类群的尺寸明显大于它们在典型地区的近亲,这与之前对该环境中腕足动物的研究一致。这些腕足动物生活在一个营养丰富、独特的环境中,与铁矿石沉积有关,这与海底以前的热液活动有关,这可能是这些腕足动物体型大的原因。以前曾在该地区记录过比正常大的 rhynchonellide 和 terebratulidine 腕足类动物。UUID:http://zoobank.org/353882-2838-4eb7-b21a-8cc665d13408
