Abstract Multituberculata from the Lower Cretaceous (Barremian–Aptian) Balve locality in Germany are represented by two taxa, the pinheirodontid Bructerodon alatus gen. et sp. nov. and the eobaatarid Cheruscodon balvensis gen. et sp. nov. Bructerodon alatus gen. et sp. nov. is known from an upper premolar (P5) and an upper molar (M1) with a distinct distolingual wing showing three cusps. Cheruscodon balvensis gen. et sp. nov. is represented by a dentary fragment with p4 and isolated teeth (P1, p4, m2). The new taxon is similar to other eobaatarids by its small single-rooted p2, double-routed p3, p4 with a single distolabial cusp, and mesio–distally asymmetric lower molars. It differs from most other eobaatarids by a larger number of serrations (11) and a larger distolabial cusp on p4. Cheruscodon gen. nov. is similar to Arginbaatar from the Lower Cretaceous of Mongolia in having the roots of p4 exposed above the alveolar border and a mesially curved distal root of p4.

德国下白垩纪第一批多瘤哺乳动物

摘要 来自德国下白垩统 (Barremian-Aptian) Balve 地区的多瘤菌以两个分类群为代表，即 pinheirodontid Bructerodon alatus gen。等 sp. 十一月 和 eobaatarid Cheruscodon balvensis gen。等 sp. 十一月 Bructerodon alatus gen。等 sp. 十一月 从上前磨牙 (P5) 和上磨牙 (M1) 得知，具有明显的异舌翼，显示三个牙尖。Cheruscodon balvensis 基因。等 sp. 十一月 由带有 p4 和孤立牙齿 (P1, p4, m2) 的牙齿碎片表示。新分类群与其他 eobaatarids 相似，具有小的单根 p2、双路径 p3、具有单个远唇尖的 p4 和近远中不对称的下臼齿。它与大多数其他 eobaatarids 的不同之处在于更多的锯齿 (11) 和 p4 上更大的离唇尖。Cheruscodon gen。十一月
