    Multidisciplinary research based on the interpretation of data acquired by archaeological and natural science methods and their correlation. The main objective is to reconstruct the interaction of factors of the environment and the living conditions of human communities and their development from the 6th until the early 12th century. The study will draw on research of the complex of the Great Moravian centre at Pohansko near Břeclav (South Moravia), its surroundings and hinterland. The subsistence strategy and its development in the early medieval society was studied on the basis of finds related to farming production and the subsequent processing of the products.

    The Early Miocene Merkur−North locality (MN 3a) represents the oldest known Miocene ophidian locality in Europe east of Germany. The snake assemblage is characterised by high species diversity and includes the following families: Boidae (Bavarioboa sp.), Colubridae (Coluber dolnicensis, Coluber suevicus, Coluber caspioides, cf. Elaphe sp., Natrix merkurensis sp. nov., Natrix sansaniensis), Elapidae (Elapidae gen. et sp. indet.), and Viperidae (Vipera sp.—“Vipera aspis” complex). Fossils of the extinct species, Coluber dolnicensis, Coluber suevicus, and Natrix sansaniensis, represent their earliest known occurrences. The cranial elements of C. suevicus and N. sansaniensis are described for the first time. Discoveries of cf. Elaphe sp. may represent the earliest fossil member of the genus Elaphe. Elapidae gen. et sp. indet. probably represents the oldest known member of the cobras.

    The two fossiliferous karst localities of Mokra´-Western Quarry, Czech Republic (MWQ, 1/2001 Turtle Joint and MWQ, 2/2003 Reptile Joint) have provided a rich herpetofauna (amphibians and squamates) from the upper part of the Early Miocene (MN 4b). Here, we describe the unpublished turtle material recovered from the above-mentioned sites, as well as two other localities of equal age including the Turtle Cave (MWQ) and a karstic fissure no. 3/2005 (Mokra Central Quarry, MCQ), which yielded two taxa attributed to Ptychogaster (Ptychogaster) cf. buechelbergense and Testudo (Chersine) cf. angustihyoplastralis. It is noteworthy that the presence of this ptychogasterid species was recently reported from several localities of NW Bohemia in Schaffer’s PhD, but unfortunately, it has never been studied in detail. In turn, Testudo cf. angustihyoplastralis represents the second known record of this taxon in Czech Republic (apart from the Austrian type-locality). Regarding the taxonomical adscrip...

    El conocimiento sobre las tortugas gigantes fósiles de Europa se ha incrementado considerablemente en los últimos años y ha comportado la descripción del género Titanochelon para incluir a las especies del Neógeno europeo. Sin embargo, la inclusión de la tortuga gigante de las Islas Baleares, “Testudo” gymnesica, en este género se ha llevado a cabo solo de forma tentativa. Con el objetivo de aclarar el estatus taxonómico y la posición filogenética de esta especie, en este artículo describimos y figuramos en detalle su material tipo (lectotipo y paralectotipos), procedente de Menorca, junto con algunos restos inéditos no incluidos en la descripción original. Las notables diferencias postcraneales que presenta esta especie con respecto a Titanochelon spp. arrojan aún mayores dudas sobre su inclusión en este género. Un análisis cladístico no resuelve sus relaciones filogenéticas. Algunos de los rasgos particulares observados en el espaldar y en los huesos del esqueleto postcraneal de l...

    Old slags situated in the areas of former exploitation of polymetallic ore mineralization are places where initial steps of soil evolution in specific conditions can be investigated. Two soil profi les of different age have been studied in the Utín (2nd half of 13th century to 1st half of the 14th century) and Dlouhá Ves (60’s of 20th century) localities. Soil samples of fine fraction were studied including vertical distribution of selected elements (Fe, Pb, As, Ag, Cu; AAS) in context to other soil parameters including loss on ignition (LOI), sequential extraction analysis (SEA), soil exchangeable acidity (pH/KCl), mass specific (χ) and frequency dependent (χFD) magnetic susceptibility. There were higher concentration of Pb (up to 4,700 ppm), Cu and Ag (both up to 100 ppm) in the Utín soils observed mostly in upper part of the soil profile. Arsenic contamination occurs in entire soil profile with average concentration about 3,000 ppm. In the Dlouhá Ves soils, the higher concentrati...

    Revisory research of floral and animal assemblages from the Neanderthal site of Gánovce-Hrádok confirmed the previous stratigraphic division of the travertine mound to five horizons on the basis of different petrological and palaeontological contents, indicating climatic and palaeoenvironmental changes in the vicinity, from the Saalian termination to the Holocene. At least two species of molluscs and approximately 20 taxa of vertebrates have been determined, and at least 8 endocasts of large mammals have been re-discovered. Revised floral record contained 570 specimens, but no more than 20% were suitable for taxonomic revision.

    The karst phenomena in the Upper Paleozoic limestones, including continental and marine Miocene sediments with associated fauna, were studied in quarries worked by Mokrá Cement Works, Inc. Mokrá Plateau, southern part of the Drahany Upland, Czech Republic. Continental sediments in the karst joints yield vertebrates indicating the upper part of the Early Miocene, especially the mammal zone MN 4. The amphibians and reptiles represent a typical assemblage from the Early Miocene climatic optimum. Mokrá quarries represent a locality with continental assemblages consisting of ecologically different taxa (a dry karst landscape with open steppe vegetation, a lacustrine environment and swampy biotopes with stagnant to moderately-flowing waters). For the first time, representatives of the Early Miocene Varanus, among the most early European occurrences of this genus, are documented in the eastern part of Central Europe. However, the abundance of moschids is the most interesting phenomenon, si...

    Herpetologické společenstvo lokality Mladeč 2 (Mladečské jeskyně: Morava, Česká republika) je typickým příkladem výrazně interglaciálního společenstva posledního teplého výkyvu holsteinského komplexu. Doloženo je celkem 12 taxonů z této lokality: Triturus cf. cristatus, Triturus vulgaris, Rana temporaria, Bufo bufo, Anguis fragilis, Elaphe longissima, Elaphe sp., Coronella cf. austriaca, Natrix natrix, Natrix cf. tessellata, Natrix sp. a Vipera berus. Herpetologické společenstvo indikuje lesostepní prostředí s bažinatými biotopy a aktivními toky v blízkém okolí. Teploty byly obecně vyšší než dnes, a ačkoliv vysoké průměrné teploty jsou typické pro poslední teplý výkyv holsteinského komplexu, nebyly odsud doloženy žádné mediteránní taxony herpetofauny. Absence zástupců mediteránní herpetfauny je ve střední Evropě (severně od Panonské nížiny) zřejmá již od počátku cromerského komplexu.

    Mladeč caves is a complex cave system that includes two key paleoanthropological findspots of Early Upper Paleolithic age - Mladeč Ib, Mladeč II, and probably also site Ia, discovered during the 19th and early 20th century. The dynamics of sediment deposition and transport inside the system is still being debated. Here we contribute new field observations from three peripheral locations within the cave system demonstrating various earlier and later cases of redepositions of Pleistocene and Holocene sediments, together with faunal remains, inside vertical fissures or chimneys. Human activity is only evidenced indirectly at these new sites, as probable manipulation with Helix shells or burning of animal bones.

    Relatively high concentrations of As (up to 47 ppm), Mo (up to 26 ppm), Hg (up to 1.4 ppm) and S (0.2 wt.%) were found based on the study of the chemical composition of the topsoil (A-horizon). Areas with high concentrations of these elements are located along the western edge the Boskovice Furrow. The areal extent and degree of anthropogenic contamination of the topsoil by several potentially toxic elements As, Mo, Hg and S can be interpreted as result of a combination of long-term coal burning especially in the thermal power plant Oslavany (apparently together with local heating) and dust emissions from coal mining. Chemical composition of power plant slag and ash indicates that a significant holder of contamination (mainly As and Mo) was fly ash, however high concentrations are also present in airborne dust generated from coal and coal claystone. Deposition solid particles (ash and coal), wear accompanied by the aerosols and gaseous emissions.
