Abstract

A well-preserved carapace of the crustacean Halicyne is here described. The finding comes from the Sostegno Basin (Piedmont, Italy). This is the first occurrence of a well-preserved arthropod from the Middle Triassic San Salvatore Formation of the Biellese area and the first report of a Triassic Cyclida from Italy. Cyclida often occurs in shallow marine environments with rapidly changing salinity conditions. The finding from the Sostegno area suggests a hypersaline paleoenvironment similar to that of Monte San Salvatore (Ticino, Switzerland) upper levels, where the same taxon was previously documented. These fossiliferous localities are shortly compared with that of Rasa di Varese (Lombardy, Italy).

意大利三叠纪最早的独眼巨人

本文描述了一种保存完好的甲壳类动物 Halicyne 的甲壳。该发现来自索斯特格诺盆地（意大利皮埃蒙特）。这是首次在比埃利塞地区三叠纪中期的圣萨尔瓦多地层中发现保存完好的节肢动物，也是意大利首次报道三叠纪的Cyclida。Cyclida通常出现在盐度条件快速变化的浅海环境中。索斯特格诺地区的这一发现表明，这里的古环境与圣萨尔瓦多山（瑞士提契诺州）上层类似，之前在那里也发现过相同的分类群。这些化石产地不久将与 Rasa di Varese（意大利伦巴第）的化石产地进行比较。

期刊介绍： The Swiss Journal of Palaeontology publishes original research and review articles of interest to the international community in the fields of palaeontology, taxonomy and systematics, while recognising at the same time the importance of documenting high-quality palaeontological data in a regional context. Palaeobiology in combination with alpha taxonomy is a core topic of the journal. Submitted papers should have an appeal as wide as possible, directed towards an international readership. Contributions should not have been simultaneously submitted elsewhere, and the overlap of content between related articles should be minimal. Duplications of text and the use of previously published illustrations without adequate citation are unacceptable. If a manuscript has two or more authors, both or all have to sign to confirm they all were involved in the work and have agreed to its submission. The preferred manuscript language is UK English, but consistently used US English is also acceptable. We encourage the publication of proceedings of international meetings as well as special thematic issues. Short contributions and book reviews are also accepted. An international editorial team as well as guest editors guarantee that the thematic issues as well as all articles in regular issues are peer-reviewed and meet the highest standards.
