Abstract The record of Middle Ordovician (Oretanian, ca. Darriwilian 2) hyolithids from the Ossa Morena Zone of the Iberian Massif in southwestern Spain is increased with the recognition of Robardetlites sevillanus n. gen. n. sp., Andalucilites parvulus n. gen. n. sp., Pauxillites desolatus n. sp., Leolites malinkyi Marek and Gutiérrez-Marco n. sp., and Cavernolites sp. in that region. Andalucilites n. gen. and Robardetlites n. gen. are endemic whereas the other genera are known from coeval strata in the Barrandian region in central Europe, France, and Morocco, giving this assemblage a decidedly “Mediterranean province” character. The discovery of Pauxillites, Leolites, and Cavernolites in Iberia extends their geographic ranges to that region, and Leolites from this area extends its stratigraphic range downward, making its occurrence in Iberia the oldest known for that genus.

Rediscovery of Branson and Mehl's (1933b) classical outcrop of the Middle Ordovician Joachim Dolomite near Holstein in eastern Missouri, from which they described 32 new species and four new genera of conodonts, makes it possible to obtain the large topotype collections needed to interpret their taxa in terms of modern multielement taxonomy. Of special interest in their Holstein fauna is Phragmodus primus Branson and Mehl, 1933, by original designation the type species of Phragmodus Branson and Mehl, 1933, whose morphology and relationships have been very poorly understood. Study of topotype collections, as well as of Branson and Mehl's syntypes, has failed to reveal any notable morphological differences between the elements of P. primus and those of P. undatus Branson and Mehl, 1933, a very well known and widely distributed species in the Middle and Upper Ordovician Midcontinent Realm faunas. These species are herein considered to be synonymous. Because the original descriptions of P. primus and P. undatus were published simultaneously, neither name has priority over the other. However, P. undatus has figured far more prominently in the taxonomic and biostratigraphic conodont literature than P. primus and therefore we favor use of the former designation for this species. The recognition that P. primus and P. undatus are the same species extends the stratigraphic range of P. undatus downward to considerably below the Deicke K-bentonite, that is, well into the Blackriveran.

Abstract This paper attempts to show that manufacture of Micoquian bifacial backed tools was structured. Data for this study were collected using a comprehensive analysis of artefacts from the site Pietraszyn 49a, Poland, which is dated to the beginning of Marine Isotope Stage 3. Based on the whole data set, it was possible to distinguish four stages of the manufacturing process. During manufacturing, both mineral hammer and organic hammer were used. The tools were usually shaped due to distinct hierarchization of faces. The study has also shown that the shape of bifacial tools from Pietraszyn 49a is very similar to the other Micoquian examples from central Europe. The ways of shaping of some tools are finding their counterparts also in the Early Upper Palaeolithic inventories, but the similarities are rather limited to the narrow range of preparation of bifacial form.

The structure of the earth was supposed by Suess to be tripartite, there was an outer layer of rocks mainly granitic, the sal, or sial as it is usually now called. This rested, or “floated”, on a dense layer called the sima, of basaltic character, within which was the earth’s core, or nife, metallic in nature. Such a simple conception has been modified in the light of later knowledge: geologically there is much evidence pointing to the existence of several shells of increasing density within the crust. This is to some extent supported by the evidence of seismology, the layers below the upper sedimentary layer being the Granitic, the Intermediate (of tachylyte or diorite) and Lower Layers (dunite, peridotite, or eclogite) (1). According to the latest information there are four layers intermediate between the granitic and lower layers: the thickness of the sedimentary layer varies from about 2 to 6 kilometres in mountainous regions: the thickness of the granitic layer varies, being about 10 to 12 kilometres in Central Europe. In low-lying regions the total thickness of these two layers is probably about 6 kilometres less than in mountainous regions: “the thicknesses of the other layers are very difficult to determine; the upper two probably have together a thickness of about 15 kilometres, but the others can hardly be determined from the observations” (2).

The Pratt Ferry beds are a three meter thick bioclastic carbonate unit containing thePygodus serrus–P. anserinusconodont zone boundary and lying just below theNemagraptus gracilisgraptolite zone at a single locality in Alabama.TelephinaMarek at Pratt Ferry and other eastern North American localities is represented by at least six species. These are judged widespread and in part conspecific with Scandinavian or Asian forms of similar age. Most of the fifteen Appalachian telephinid species proposed by Ulrich (1930) are reviewed and some synonymized.BevanopsisCooper is present, extending its stratigraphic range viaB. buttsi(Cooper). The original description ofCeraurinella buttsiCooper is augmented. Other recorded but poorly represented genera includeAmpyxina,Arthrorhachis,Calyptaulax,Hibbertia,Lonchodomas,Mesotaphraspis,Porterfieldia, andSphaerexochus. The entire faunule represents a mixture of ‘inshore’ and ‘offshore’ or planktonic faunal elements rarely seen elsewhere in the latest Middle Ordovician (Darriwilian) of eastern North America.

This article, which is based on the fourteenth McDonald Lecture, considers two tensions in contemporary archaeology. One is between interpretations of specific structures, monuments and deposits as the result of either ‘ritual’ or ‘practical’ activities in the past, and the other is between an archaeology that focuses on subsistence and adaptation and one that emphasizes cognition, meaning, and agency. It suggests that these tensions arise from an inadequate conception of ritual itself. Drawing on recent studies of ritualization, it suggests that it might be more helpful to consider how aspects of domestic life took on special qualities in later prehistoric Europe. The discussion is based mainly on Neolithic enclosures and other monuments, Bronze Age and Iron Age settlement sites and the Viereckschanzen of central Europe. It may have implications for field archaeology as well as social archaeology, and also for those who study the formation of the archaeological record.

An assemblage of axiidean and brachyuran decapods is reported from the late Miocene pre-evaporitic (early-middle Messinian) limestone of Cò di Sasso, nearby Brisighella (Ravenna, Emilia- Romagna), located in Romagna Apennines (NE Italy). Except Monodaeus bortolottii Delle Cave, 1988 (Xanthidae MacLeay, 1838), which is reported here for the first time in Miocene, all the other specimens have been assigned to species previously known in the Italian Miocene (Messinian s.l.), but never reported in this area. The report of Galathea cf. G. weinfurteri Bachmayer, 1950 (Galatheidae Samouelle, 1819) and Medorippe ampla Garassino, De Angeli, Gallo and Pasini, 2004 (Dorippidae MacLeay, 1838) enlarges the stratigraphic range of these Miocene species. This report enlarges our limited knowledge on the composition and distribution of the axiidean, anomuran, and brachyuran decapods during the early-middle Messinian before the evaporitic event in the Mediterranean Basin.

Among the archaeological remains of central Europe there are some of quite distinct Scythian character. They testify the presence of the Scythian nomads on that territory in the period about 500 B.C. Besides, the fact that the dating of those remains is quite well established should provide a basis for the proper dating of those central European cultures which came into contact with the Scythians.The Scythian remains in central Europe are divided into two groups. To the first group belong the remains found in limited areas, with Scythian graves among them; those remains enable us to establish local groups of Scythian culture. The other group occurs among the remains of other, non-Scythian, cultures where they arrived either by way of peaceable trade exchange or were brought there by the Scythians themselves during their invasions or inroads into those territories.In this short article I do not intend to give any detailed description of the Scythian remains in central Europe or to give an appreciation of their artistic value. They do interest me, but only as evidence of certain historical happenings, and I refer to the works of Professor E. H. Minns, Professor M. Rostovtzeff, Dr. N. Fettich, and others for their dating.

After the collapse of communism, the countries of Central Europe, including Poland, be-came a “buffer zone” for the European Union. This was not the result of a deliberate policy by the EU; Poland and the other countries in Central Europe wanted to begin cooperation with the EU as soon as possible, hoping to become its members.Future membership in the Union required Poland to adopt and implement the regulations of the Schengen legal order, which included control on its external borders, a common visa regime, combating cross-border crime, migration policy, infrastructure for border protection, as well as cooperation of border, customs and police services. Adopting the EU standards formed the basis for drawing up and implementing strategic governmental projects: The Action Plan for the Implementation of the Schengen Legal Heritage in Poland as well as the Strategy for the Integrated Border Management.Membership in the EU entailed a wide range of legal, institutional and infrastructural adjustments along the Polish and Russian border, as Poland came to be responsible for the safety of each specific section of the external border. In order to meet the Schengen regulations on the Polish and Russian border, the authorities of the Province of Warmia and Mazury began implementing projects and plans for managing the national border with respect to modernising its infrastructure and construction of border crossings. On the other hand, The Warmia and Mazury Division of the Border Guard took action in border protection consisting in adjusting border protection standards to the border crime threats, illegal migration as well as the intro-duction of regulations to allow for free transfer of persons and objects across the border.

Abstract. ‘Globigerina Ooze’, Foraminiferal Ooze or Carbonate Ooze as it is now known, is a widespread and highly characteristic sediment of the modern ocean system. Comparable sediments are much less common in the geological record although, as we describe here, a number of Middle Jurassic carbonate sediments with distinctive assemblages from Central Europe fulfil many of the criteria. One important component of these assemblages in the Middle Jurassic is ‘Globigerina bathoniana’ Pazdrowa, 1969, first described from the Bathonian sediments near Ogrodzieniec (Poland). The generic assignment of this species and other coeval Jurassic taxa is discussed. This species and many of the other early planktic foraminifera evolved in the Aragonite ll Ocean, together with the other two oceanic carbonate producers: the calcareous nannofossils and the calcareous dinoflagellates. The preservation of carbonate sediments with abundant planktic foraminifera on the sea floor indicates that, by the mid-Jurassic, the carbonate/aragonite compensation depths (and associated lysoclines) must have developed in the water column.
