Abstract

A new finding of a coelacanth from the upper Ladinian upper Kalkschieferzone of the Meride Limestone Formation of Monte San Giorgio (UNESCO World Heritage area) is described. It represents the first known coelacanth from the Middle Triassic that undoubtedly bears elongate thin ribs. The incompleteness of the specimen prevents a reliable taxonomic assignment or the erection of a new species, however some characters, mainly scale morphology, are very similar to those of the holotype of Heptanema paradoxum Bellotti, 1857 from the roughly coeval Perledo Formation of Northern Italy. Elongate ribs are not reported in original descriptions of H. paradoxum, however small portion of ribs are visible among the scales of the holotype. Accordingly, the new specimen is tentatively ascribed to Heptanema as Heptanema cf H. paradoxum.

瑞士蒂西诺州圣乔治山中三叠世(拉丹)KALKSCHIEFERZONE的一个长肋腔棘鱼新标本
描述了在圣乔治山梅里德石灰岩组(联合国教科文组织世界遗产区)的上拉迪尼亚-上卡尔克斯基耶弗地带发现的一种腔棘鱼。它代表了已知的第一只三叠纪中期的腔棘鱼,毫无疑问地长着细长的肋骨。标本的不完整性阻碍了可靠的分类学分配或新物种的建立,然而,一些特征,主要是鳞片形态,与1857年意大利北部大致同时代的佩莱多组的赫塔内马悖论贝洛蒂正模非常相似。在对H.paradocum的原始描述中没有报道细长的肋骨,但在正模的鳞片中可以看到一小部分肋骨。因此,这个新标本被初步认定为正庚烷属,名为Heptanema cf H.paradoxum。
