Abstract The features and distribution of Coniacian terebratulides from the Northern Castilian Platform (Northern Spain) have been studied. Simultaneously, an exhaustive revision of European Upper Cretaceous brachiopod collections has been developed, allowing to define new species and to propose some lectotypes. Four species of the genus Nucleatina Katz, 1962, have been identified in the study area: N. arcana sp. nov., whose range is restricted to the basal and lower Coniacian (Forresteria petrocoriensis and Tissotioides haplophyllus zones), is characterized by its small size and “graphillate” ornamentation; N. anotia sp. nov. is ranged in the middle Coniacian (Gauthiericeras margae zone), differenced by its “capillate” ornamentation; N. cristobali (Middlemiss, 1978) appears in the upper middle and basal upper Coniacian (Gauthiericeras margae and Hemitissotia turzoi zones), being distinguished by the presence of two lateral expansions with auricular shape on both sides of the dorsal umbo; and N. barrosoi sp. nov., which appears in the upper Coniacian (Hemitissotia turzoi zone), is characterized by its larger size and fine striation. The genus Kafirnigania Katz, 1962, has been also identified, being the first record in Western Europe: K. massiliensis sp. nov., with smaller beak, is distinguished in the lower Coniacian (Tissotioides haplophyllus zone); and K. jorali sp. nov., with bigger beak and cardinal area, recorded in the middle Coniacian (Gauthiericeras margae zone). The species here described appear in Northern Spain, although N. anotia and N. cristobali are possibly present also in the Aquitaine Basin (Southwestern France), and K. massiliensis also appears in the Mouths of the Rhone, Southeastern France.

来自西班牙北部的 Coniacian (上白垩纪) Terebratulides (Brachiopoda)

摘要 研究了北卡斯蒂利亚地台（西班牙北部）Coniacian terebratulides 的特征和分布。同时，对欧洲上白垩纪腕足动物收藏进行了详尽的修订，允许定义新物种并提出一些选型。Nucleatina Katz 属的四个物种，1962 年，已在研究区被鉴定出来：N. arcana sp.。nov.，其范围仅限于基部和下部 Coniacian（Forresteria petrocoriensis 和 Tissotioides haplophyllus 区域），其特点是体积小和“石墨”纹饰；N.anotia sp. 十一月 位于 Coniacian 中部（Gauthiericeras margae 区），区别在于其“毛细管”纹饰；N. cristobali (Middlemiss, 1978) 出现在中上部和基部上部 Coniacian (Gauthiericeras margae 和 Hemitissotia turzoi 区)，其特征是在背伞的两侧存在两个具有耳形的横向扩展；和 N. barrosoi sp。11 月，出现在上 Coniacian (Hemitissotia turzoi 区)，其特点是其较大的尺寸和细条纹。Kafirnigania Katz 属，1962 年，也已被确定，是西欧的第一个记录：K. massiliensis sp。11 月，喙较小，在下部 Coniacian（Tissotioides haplophyllus 区）中很明显；和 K. jorali sp。11 月，喙和基区较大，记录在 Coniacian 中部（Gauthiericeras margae 区）。这里描述的物种出现在西班牙北部，尽管 N. anotia 和 N.
