Archaeology by Jörg Ansorge
contents were determined by μ-X-ray diffraction and polyenes as red dyes were detected by μ-Raman spectroscopy. Additionally, the characteristic dense volume structure of Corallium rubrum were imaged by high-resolution μ-X-ray computed tomography. Strontium and boron isotopies were determined by mass spectrometry
being evident for a recent formation under marine conditions. These data are compared with coral artefacts from other Hanseatic cities proving their economic and cultural interdependencies. Related materials e.g. of Iron Age fibulae beads and from ethnographic objects from Africa, were additionally characterized for to differentiate red Corallium rubrum from anthropogenetic whitened or orginal white Corallium rubrum, neomorphic calcites from aragonite, as well as from chemical sedimentary calcites.
Töpfers Hans Krevet, dessen Testament im Stadtarchiv Stralsund den Beleg für die Zugehörigkeit der eingeschnittenen Hausmarke erbrachte. An metallischen Kleinfunden sind 37 Münzen und zwei Rechenpfennige, zahlreiche Tuchplomben
sowie vier Überreste von Nürnberger Zapfhähnen zu erwähnen. Aus Schichten des 17. Jahrhunderts stammt die Tülle einer Raerener oder Westerwälder Tüllenkanne aus dem Umfeld des Jan Emens (um 1590).

Foraminifers, ostracods, molluscs, plant remains, vertebrates and archaeological finds of all kind were used to establish a reliable model of coastal site development at the shore of the Strelasund from about 5300 BC to the 1860s AD, comprising naturally induced environmental changes and human impact and providing new insights into the coastal evolution and harbour transformations in Stralsund of the past seven millennia.
The clam species Mya arenaria, introduced by human activities into the Baltic Sea, proved to appear not earlier than in the 17th century in this region.
Besides a diverse ichnofauna and a few vertebrates, numerous fossil insects were recorded. The microfauna of the cementstones contains marine diatoms and agglutinated foraminiferans of which many were digested and broken by sediment feeders The Pleistocene succession comprises a Saalian till at the basis and overlaying Weichselian tills and glacialfluvial sediments. New stratigraphical and palaeontological investigations revealed a brackish-marine clay with microfossils of an Early to Middle Weichselian marine ingression into the Pomeranian Bay. Furthermore, recent processes of coastal dynamics can be observed on the Greifswalder Oie that led to formation of a sandy spit and a large riff on the eroded SW part of the island which is now covered by large erratic boulders. However, the coastal erosion and accumulation of sediments has been changed after a protecting sea wall was built at the turn from 19th to 20th century. Rather unique is the composition of erratic boulders originating from various areas in northern Europe. A few of them are worth to be classified as protected geosites.
Zwei bisher unbeschriebene subfossile Pilzfruchtkörper (Baumschwämme, Porlinge) aus dem Quartär Vorpommerns, Nordost-Deutschland, werden beschrieben: Fomes fomentarius aus der späten Litorina-Zeit (etwa 7300 Jahre BP) von einer Baugrube in Stralsund ist wahrscheinlich der größte jemals dokumentierte fossile / subfossile Pilzfruchtkörper überhaupt. Phellinus igniarius agg. liegt aus einer jungquartären Torfschicht bei Damerow (Insel Usedom) vor. In beiden Fällen waren die Fruchtkörper vollständig erhalten, und es konnte keine Beziehung zu menschlichen Siedlungen aufgezeigt werden.
Scandinavian export goods. In the Viking and Slavian Age cooking pots and other articles of soapstone, shist honestones (Eidsborg) and millstones of garnet micashist were exported from Norway. With the beginning of the hanseatic trade in the 13th century coralline limestone from Gotland, orthoceras
limestones from Oeland and Danien limsten were used in huge extent as building stones and raw material for lime burning in the Southern Baltic region. Upper Devonian Platychisma dolomite
found at the medieval brick yard at Wackerow near Greifswald is ship ballast from Latvia. In the 19th century Swedish granite was used as cobble stones in the Baltic coastal towns. Rare
rhomboidal porhyries in the cobble of Greifswald originates from ship ballast, picked up near the source area in the Oslo graben. At the end of the 18th and in the 19th century porphyries from
Dalarne were worked in a stonemill at Älvdalen, the goods were exported all over Europe. English hard coal was used since the 13th century in the hanseatic towns of Greifswald and Stralsund by blacksmiths, it was also used to mark real properties boarders in the country side.
Approximately 160 pilgrim badges found in Stade come from twenty-six identified pilgrimage sites in Middle Europe. About a dozen sites are still awaiting identification. These findings overturn much received scholarship on late medieval pilgrimage in northern Germany and suggest instead the emerging contours of an understudied, dynamic, late medieval landscape of pilgrimage.
A pilgrim badge from the westfalian castle church of Stromberg was found in Rostock dated at 1269 AD.
