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石灰石”是侏罗纪已故的全球最重要的化石lagerstätte之一。但是，通常被共同称为“ Solnhofen动物群”的化石实际上源自许多地方，代表不同的沉积环境和不同的时间范围，从晚期的Kimmeridgian到早期的Tithonian。由于我们对这些不同地区的地质和地层框架的一般了解，这是一个独特的机会，可以在地质上短时间内研究区域侏罗纪生态系统的进化动态，但是“ Solnhofen Fauna”的这一方面已经很大程度上忽略了。在我们正在进行的研究中，我们目前正在尝试在Solnhofen群岛内不同地区的脊椎动物动物区系之间建立差异和相似之处，从这种情况下，Oberpfalz的Brunn，最古老的地方开始。该位置的爬行动物动物群相当差，对其他地点显示出显着的分类差异，这可能是由于该地区与其他地方之间的地层差异所致。但是，为了确定这是否是布鲁恩脊椎动物动物区系中看到的一般模式，我们需要来自该地点的更丰富的鱼动物区系中的数据。因此，当前提案的目的是概述布鲁恩的鱼类动物区系的系统和分类组成，并将其与索尔诺夫群岛中其他地区的动物区系进行比较。结果显示与其他动物群落的差异和相似性对于解释导致不同动物联想的进化过程的核心至关重要。
