'Orsten' fossils

奥斯滕代表了一种独特的保存方式，主要是寒武纪的后生动物化石的三维保存。它们最初是在瑞典发现的，现在在世界范围内都有发现。然而，到目前为止，研究重点主要集中在节肢动物化石上。在我们的新项目中，我们将调查瑞典东部所有剩余的微化石材料。有五个不同的组成部分需要研究：1)incertae sedis微化石；2)假定的“小壳类化石”；3)至今未发现的节肢动物；4)丝状结构，5)蠕虫状化石。我们的目标是全面记录分类和生物多样性，同时增加与其他类似地点/动物群落的可比性，并更好地了解这些化石材料的分类学，不仅仅是为了未来的探索。这在古地理方面也很重要，因为在冈瓦纳巨型大陆上仍然缺少这样的化石材料，冈瓦纳大陆在那个时候存在，并且部分靠近一些沿海地区，这些地区已经报道了奥斯滕型化石。

, 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.
