, Orsten stands for a unique type of preservation of three-dimensionally preserved metazoanfossils from mainly the Cambrian. Originally described from Sweden, they are foundnow on a worldwide scale. Yet, until now the focus was mainly on arthropod fossils. In ournew project we will investigate all remaining microfossil material of the, Orsten of Sweden.There are five different components to be studied: 1) incertae sedis microfossils; 2) putative„small shelly fossils ; 3) remains und hitherto unknown arthropods; 4) thread-like structures,and 5) worm-like fossils. Our aims are a comprehensive documentation of the taxaand biodiversity, also to increase comparability with other such localities/faunal communities,and to achieve a better understanding of the taphonomy of such fossil material, notleast for future explorations. This is also important in palaeogeographic respect becausesuch fossil material is still missing from the mega continent Gondwana, which existed atthat time and was partly close to some of the coastal areas form which, Orsten -type fossilshave been reported.

Orsten代表了一种主要来自寒武纪的三维保存的后生动物化石的独特保存类型。最初在瑞典被描述，现在在世界范围内被发现。然而，到目前为止，焦点主要集中在节肢动物化石上。在我们的新项目中，我们将调查瑞典奥斯滕所有剩余的微体化石材料。有五个不同的组成部分需要研究：1）不确定的sedis微体化石; 2）假定的“小壳化石”; 3）迄今未知的节肢动物遗骸; 4）线状结构; 5）蠕虫状化石。我们的目标是一个全面的taxaand生物多样性的文件，也增加与其他这样的地方/动物群落的可比性，并实现更好地了解这种化石材料的埋藏，尤其是为未来的探索。这在古地理学方面也很重要，因为这样的化石材料在冈瓦纳大陆上仍然缺失，冈瓦纳大陆当时就存在，并且部分靠近一些沿海地区，据报道有奥斯滕型化石。
