| 摘 要： | Nieper(1969)依据澳大利亚 Queenslaad 西部 Nora 组(下奥陶统)的标本以 Trigonodus triangularius Nieper 1969 为模式种,建立了牙形刺新属 Trigonodus. Cooper(1981)将 Nieper 的形式属 Trigonodus 修正为器官属,包括 PM Sa Sb Sc Sd 分子,并将此属的模式种改为 Trigonodus larapintinensis (Crespin, 1943). Cooper 的观点被很多牙形刺专家接受, Trigonodus 属名也被广泛引用在牙形刺文献中 (Stauge, 1984;安泰庠、郑昭昌,1990),

| Abstract: | Trigonodus, established by Nieper (1969) for Lower Ordovician conodonts, is an invalid name, because it was preoccupied by the famous bivalve genus Trigonodus Sandberger in Alberti, 1864. All conodonts previously assigned to Trigonoclus should be transferred to Triangulodus van Wamel., 1974, or to Pteracontiodus Harris et Harris, 1965. |
