The so-called "Solnhofen limestones" are one of the most important fossil lagerstätte of the Late Jurassic globally. However, the fossils that are often collectively called the "Solnhofen fauna" are actually derived from numerous localities, representing different depositional environments and different time horizons, spanning from the Late Kimmeridgian to the Early Tithonian. Due to our generally excellent understanding of the geological and stratigraphic framework of these different localities, this lagerstätte represents a unique opportunity to study the evolutionary dynamics of a regional Jurassic ecosystem over a geologically short span of time, but this aspect of the "Solnhofen fauna" has largely been neglected so far. In our ongoing research, we are currently trying to establish differences and similarities between the vertebrate faunas of different localities within the Solnhofen archipelago, starting with the oldest locality in this setting, that of Brunn, Oberpfalz. The rather poorly represented reptile fauna of this locality shows significant taxonomic differences to other sites, which might be due to the stratigraphic difference between this and other localities. However, to decide whether this is a general pattern seen in the vertebrate fauna of Brunn, we need data from the much more abundant fish fauna from this site. The aim of the current proposal is thus to give an overview of the systematic and taxonomic composition of the fish fauna from Brunn and compare it with the fauna of other localities within the Solnhofen archipelago. The results showing differences and similarities to other faunas will be of central importance for interpretations of the evolutionary processes that led to the different faunal associations.

所谓的“Solnhofen石灰岩”是全球最重要的晚侏罗世化石之一。然而，通常被统称为“Solnhofen动物群”的化石实际上来自许多地方，代表不同的沉积环境和不同的时间范围，从晚Kimmeridgian到早期Tithonian。由于我们对这些不同地区的地质和地层框架有着非常好的了解，这座湖代表了一个独特的机会，可以在地质学上很短的时间内研究区域侏罗纪生态系统的演化动力学，但到目前为止，“Solnhofen动物群”的这一方面在很大程度上被忽视了。在我们正在进行的研究中，我们目前正试图建立不同地点的脊椎动物区系之间的差异和相似之处，从最古老的地方在这个设置，即布伦，上普法尔茨。该地区爬行动物区系的代表性较差，与其他地区存在显著的分类差异，这可能是由于该地区与其他地区之间的地层差异。然而，为了确定这是否是布伦脊椎动物区系中的一般模式，我们需要来自该网站的更丰富的鱼类区系的数据。因此，目前的建议的目的是提供一个概述的系统和分类组成的鱼类动物群从布伦和比较它与其他地方的动物群内的索恩霍芬群岛。显示与其他动物群的差异和相似性的结果对于解释导致不同动物群组合的进化过程至关重要。
