Abstract When naming ichnotaxa based on uncollectable trace fossils, the holotype is the actual ichnofossil in the outcrop, though some ichnologists identify the holotype as a replica (cast) held in a museum collection, and refer to it as a “plastotype,” although not all such replicas are made from plaster. Nevertheless, through its Code, the International Commission on Zoological Nomenclature (ICZN) makes it clear that an artificial, human-made replica (plaster cast or otherwise) is not eligible to be the holotype of an ichnotaxon. This directive is potentially destabilizing to much ichnological taxonomy, which is based on holotypes left in the field that have disappeared or will disappear. One possible solution for ichnologists will be to petition the ICZN to recognize that artificial, human-made replicas of ichnofossils can serve as name-bearing types. These may best be called “axiotypes” (from the Greek axios, meaning “of equal value”).

生态分类学中的“塑性型问题”

摘要 当根据无法收集的踪迹化石命名鱼类群时,正模标本是露头中的实际鱼鳞化石,尽管一些鱼类学家将正模标本识别为博物馆收藏中的复制品(铸件),并称其为“塑性标本”,尽管并非如此。所有这些复制品都是用石膏制成的。尽管如此,国际动物命名委员会 (ICZN) 通过其《守则》明确指出,人工的、人造的复制品(石膏模型或其他方式)没有资格成为鱼纲动物的正模标本。该指令可能会破坏许多 ichnological 分类法的稳定性,这些分类法基于该领域中已消失或将要消失的正模标本。生物学家的一种可能解决方案是向 ICZN 请求承认人工、人造化石的复制品可以作为带有名称的类型。这些最好被称为“axiotypes”(来自希腊语 axios,意思是“同等价值”)。
