摘要†montanensis， sp. 11 . （Teleostei: Ostariophysi: Gonorynchidae）来自美国蒙大拿州Two Medicine组晚白垩世淡水沉积物。该物种以第二个体的一具关节骨骼和部分躯干区域为代表。在北美早白垩世至中古新世的沉积物中，几乎不知道铰接淡水鱼化石。对于更好地了解早期北美淡水硬骨鱼的生物多样性，诸如双药鱼的地点是极其重要的。†Notogoneus montanensis, sp. nov.是已知最早的†Notogoneus属，也是已知最早的北美淡水淋病虫。本文简要介绍了淋球菌及其他淋球菌的分布情况。与†N相关的其他鱼类化石碎片。montanensis, sp. 11 .包括许多硬骨鱼鳞片，这些鳞片似乎至少属于两个不同的分类群，而不是†N…
ABSTRACT †Notogoneus montanensis, sp. nov. (Teleostei: Ostariophysi: Gonorynchidae) is described from Late Cretaceous freshwater deposits of the Two Medicine Formation of Montana. The species is represented by one articulated skeleton and a partial trunk region of a second individual. Articulated freshwater fish fossils are almost unknown in Early Cretaceous through Middle Paleocene age deposits of North America. Localities such as the Two Medicine fish locality are extremely important to a better understanding of the biodiversity of early North American freshwater teleosts. †Notogoneus montanensis, sp. nov. is the earliest known occurrence of the genus †Notogoneus, and it is the earliest known freshwater gonorynchiform from North America. The distribution of †Notogoneus and other gonorynchid species is briefly reviewed. Additional fragmentary fish fossils found associated with †N. montanensis, sp. nov. include a number of teleost scales, which appear to belong to at least two different taxa other than †N...
