The early Miocene marine deposits in Tierra del Fuego bear a group of struthiolariid gastropods that stand out for their high morphological variability. since the end of the 19th century this variability was interpreted as reflecting (1) a highly diversified rapidly evolving group of species or (2) a single, plastic species characterized by ample intraspecific variability. The morphological study of more than 100 specimens of the Fuegian struthiolariid genus Perissodonta Martens collected in the Carmen Silva, Viamonte, and Irigoyen formations indicate that significant parameters, such as shell shape, spire length and number of spiral and axial sculptures (cords, threads, tubercles) vary continuously within an ample range of values, favoring a single, plastic species. Topotype specimens of Perissodonta ameghinoi (Ihering), collected from the early Miocene Monte Leon Formation in Patagonia, show similar plasticity of characters. Furthermore, recent topotype material of Perissodonta georgiana Strebel from Islas Georgias del Sur, a species considered very close or junior synonym of the genotype species P. mirabilis (Smith), indicates a similar degree of plasticity. Accordingly, the Fuegian struthiolariids previously assigned to Perissodonta ameghinoi; P. fueguina (Ihering); or P. densestriata (Ihering) are here referred to P. ameghinoi, a struthiolariid gastropod restricted to the early Miocene in Tierra del Fuego and Patagonia.

The technique presented in this paper points to the recovery of three dimensional rigid casts from natural molds of fossil organisms. The study of organisms preserved as molds in the rock (usually in slabs) is difficult, even if the natural mold is high detailed. Traditionally, casts were made from each side of the natural mold, resulting in positive, soft partial specimens embedded in the rock. These kinds of casts did not solve some issues related to the preservational mode and exposure of the natural molds. The application of this technique turns a natural rigid mold into a soft silicone rubber mold to make a final three dimensional rigid cast of the whole specimen devoid of sediment. This technique provides casts that preserve the details of the natural mold. The obtained casts allow and facilitate scientific anatomical studies but also provides excellent specimens for museum exhibition or educational purposes. Key words. Silicone rubber. Resin. Replicas. Molding technique. Slabs. Museum. Resumen. REPLICAS 3D A PARTIR DE MOLDES NATURALES: UN CASO DE ESTUDIO BASADO EN FOSILES DE RANAS. La tecnica que presentamos en esta contribucion apunta a la obtencion de replicas rigidas de fosiles que se preservaron en las rocas como moldes naturales. El estudio de organismos preservados de esta forma (comunmente en lajas) es dificultoso, aun si el molde tiene una excelente preservacion. Tradicionalmente, dicha dificultad se ha resuelto realizando copias de los moldes naturales, obteniendo positivos (replicas) parciales y flexibles del especimen. Este tipo de copias facilitan el estudio pero no resuelven todos los problemas relativos a la preservacion en si misma y a la exposicion del ejemplar fosil. La tecnica que aqui desarrollamos convierte, mediante una serie de pasos intermedios, un molde natural rigido en uno flexible del que a su vez se obtienen copias rigidas, tridimensionales y libres de sedimento del especimen fosil, que conserva todos los detalles del molde natural. Las copias obtenidas sirven no solo para facilitar el estudio anatomico morfologico de los restos fosiles sino tambien como material didactico y de exhibicion de gran calidad. Palabras clave.

本文提出的技术指向从化石生物的天然模具中恢复三维刚性铸件。研究岩石(通常是石板)中以霉菌形式保存的生物是困难的，即使天然霉菌非常详细。传统上，铸件是由天然模具的每一面制成的，结果是正面的、柔软的部分标本嵌入岩石中。这些类型的铸件并没有解决一些与自然模具的保存方式和暴露有关的问题。该技术的应用将一个天然的刚性模具变成了一个柔软的硅橡胶模具，从而使整个样品的最终三维刚性铸件没有沉积物。这种技术提供的铸件保留了自然模具的细节。获得的铸件允许并促进科学解剖研究，但也为博物馆展览或教育目的提供了优秀的标本。关键字。硅橡胶。树脂。副本。成型技术。板。博物馆。Resumen。自然模型的复制品:UN caso de estudio basado和化石de ranas。这一技术对化石的复制、刚性、保存和保存都有重要的贡献。El estudio de organismos preservados de esta forma(评论en lajas)是很难做到的，因为它是一种非常好的保存方法。传统上，由于难以识别，导致无法实现对自然模型的复制，特别是对柔性模型的复制。文物保护设施和文物保护设施的建立，导致了文物保护和文物保护的问题。La tecnica que aqui desarrollamos conerte, mediante de pasos intermedios, unmodelnatural rigidas, unmodelnatural rigidas, unmodelnatural, unmodelnatural, unmodelnatural, unmodelnatural, unmodelnatural, unmodelnatural, unmodelnatural。古生物学:古生物学，古生物学，古生物学，古生物学，古生物学，古生物学，古生物学，古生物学，古生物学。Palabras劈开。矽谷。Resina。Copias。Tecnicas de molde。斯拉。博物馆。
