For the palaeo-ecological development and interpretation of the macrofauna (Bivalvia and Gastropoda) of the Eemian Sea in the southwestern Baltic Sea region (NE Germany), up to date studies and summarising assessments are largely missing. With the main goal of revising the Eemian marine fauna, the authors have undertaken numerous new samplings in recent years. This study begins by focusing on the Warnow Bay in today's Warnow valley near Rostock. In addition to examining older data from the literature, the sandpit at Schwaan and drillings of the State Geological Survey from Boitin, Reez and Rostock were studied. Parallel to this, was also undertaken pollen analyses.

Despite hundreds of drillings from the region of the former Warnow Bay, evidence of the marine Eemian was relatively rare. Apparently the sandy sediments were reworked and redistributed by glaciotectonic, glaciofluvial and fluvial processes during the Weichselian glaciation. There is as yet no definite proof of autochthonous marine sediments.

They are predominantly shallow-marine sands several meters thick which are found mostly at a depth of about 30–20 m b.s.l. but more rarely also relatively close to the surface in opencast mining or cliff sections.

The sands are rich in marine mollusc fauna of which 29 species have been identified so far and which also include Lusitanian specimens such as Acanthocardia paucicostata, Lucinella divaricata or Polititapes senescens. Account was also taken of accompanying marine fauna such as barnacles and echinoderms. In addition, the sediments contain fresh water molluscs also including the interglacial indicator species Belgrandia germanica.

对于波罗的海西南部地区（德国东北部）埃姆海大型动物（双壳纲和腹足纲）的古生态发展和解释，大部分缺乏最新的研究和总结评估。以修改 Eemian海洋动物群为主要目标，作者近年来进行了许多新的采样。这项研究首先关注今天位于罗斯托克附近的沃诺河谷的沃诺湾。除了检查文献中的旧数据外，还研究了 Schwaan 的沙坑和 Boitin、Reez 和 Rostock 的国家地质调查局的钻探。与此同时，还进行了花粉分析。

尽管从前沃诺湾地区进行了数百次钻探，但海洋 Eemian 的证据相对较少。显然，在魏氏冰川作用期间，砂质沉积物受到冰川构造、冰川河流和河流过程的改造和重新分布。目前还没有明确的证据表明本土海洋沉积物。

它们主要是几米厚的浅海砂，主要位于约 30-20 m bsl 的深度，但在露天采矿或悬崖部分的地表附近也很少见。

沙地里有丰富的海洋软体动物区系，目前已鉴定出 29 种，其中还包括 Lusitanian 标本，如Acanthocardia paucicostata、Lucinella divaricata或Polititapes senescens 。还考虑了伴随的海洋动物，如藤壶和棘皮动物。此外，沉积物中还含有淡水软体动物，其​​中还包括间冰期指示物种Belgrandia Germanica。
