Opis:: Seventeen taxa of exotic trilobites representing eight families are described from the olenid- and agnostoid-dominated strata of the uppermost Cambrian Series 3 and lower Furongian alum shale facies of Sweden and from glacial erratic boulders of Denmark. Only five taxa are assigned to species level, i.e., Maladioidella abdita (Salter, 1866), Olentella rara (Westergård, 1922), Pedinocephalus peregrinus (Henningsmoen, 1957), Ptychoparia pusilla (Westergård, 1922), and Westergaardella olenorum (Westergård, 1922), whereas the others are left under open nomenclature or remain unrecognized. Most are described for the first time from the Cambrian of Scandinavia. Their affinities point to a strong connection with East Gondwana, Laurentia, Kazakhstania and Siberia. Exotic trilobites appear in the succession directly after periods of very low oxygen concentration in the Alum Shale Sea; their occurrences correspond to the ranges of agnostoid arthropods in the succession and seem to be linked to global transgressive events causing an influx of cool and/or oxygen-depleted waters onto the shelf of the Baltica palaeocontinent.

Opis:: There is no consistency in reporting the stone material used to construct the first structures in the early Piast dominion (10–11th century) in Poland. The role and importance of the type of the stone building material used at that time has been underappreciated if not completely ignored. It has been stated that glacial erratics comprise the fundamental rock material used in the early Middle Ages for building, representing up to 98% of construction material. The remaining rocks used in building construction included local calcareous sinter, bog iron ores, Jurassic limestone from the Piechciny-Barcin region and gypsum from a salt dome in the village of Wapno in western Poland, while Miocene sandstone excavated at the inception of the Polish state in the Brzeźno Quarry near Konin has received significant attention. There appear to have been distinct phases of use of the various types of rock material. There was likely a link between the development of tillage and the development of monumental stone architecture from the Middle Ages. Deforestation resulting from the development of agriculture helped expose the glacial erratics used in the stone architecture of the first Piast rulers.

Tytuł:: The petrography of glacial sediments in Uckermark, NE Brandenburg : a preliminary study

Opis:: The Brandenburg section of the hinterland and of the maximum extent of the Pommeranian phase of the last glaciation, formed in two lobes (Schulz, 1967): Joachimsthal-Ringenwalder and Ucker-markischer, have been covered by a study on petrography of a gravelly and a stony fraction. The methods applied followed suggestions of Bose (1989), Trembaczowski (1961, 1967), Meyer (1983), Smed (1993, 1994) and Zandstra (1999). Petrographical analyses undertaken in Uckermark, NE Germany, were focused on: 1) observation of the dynamics of petrographical features along and in the hinterland of the Odra lobus on the German side, 2) indication of the western limit of the Odra lobus upon petrography of glacial sediments, 3) indication of Scandinavian parent areas of sediments of the Pommeranian phase and estimating the routes of ice-sheet onto German Lowland. The distance between outcrops of Scandinavian rocks causes the number of erratics in sediments of glacial accumulation in the German part of the Odra lobus. There are more Mesosoic rocks in the gravelly fraction as compared with sediments of the same age, but sampled in the Polish part of the Odra lobus. The stony fraction (20-60 mm) is represented mainly by indicator erratics from Smĺland and the Swedish coast in Kalmar Strait. Ĺland erratics, quite frequent in Polish lowlands, are observed rarely in Uckermark. Among statistical erratics there are numerous flints and Mesosoic limestones as well as Lower-Palaeozoic limestones. The theoretical stone centre moves its locality within middle-southern Smĺland.
