Opis:: The borings of Teredinidae in fossil wood of Taxodium distichum Gothan, 1906. Photographs of borings in fossil wood (Taxodium distichum Gothan, Miocene, Roztocze, Poland) were taken. The texture of the borings surface was analyzed. Moreover, photographs were taken of the surface texture of borings in makore wood (Tieghemella heckelii Pierre) from Africa after Teredinidae and after different species of insects in Scotch pine (Pinus sylvestris L.) for comparative purposes. The photographs were compared. The suspected wood borings in the studied fossil wood of T. distichum were made by mollusc (Teredinidae).
Tunele Teredinidae w skamieniałym drewnie Taxodium distichum Gothan, 1906. Wykonano zdjęcia faktury powierzchni ściany tuneli wydrążonych przez Teredinidae w kopalnym drewnie Taxodium distichum z Frampola (Miocen, Roztocze, SE Polska). Dla celów porównawczych sfotografowano tekstury powierzchni ściany tuneli w drewnie makore (Tieghemella heckelii Pierre) z Afryki, pozostałe w sośnie zwyczajnej (Pinus sylvestris L.) po żerowaniu Teredinidae i innych gatunkach owadów. Na podstawie porównania fotografii stwierdzono, że tunel w badanym drewnie kopalnym T. distichum został wydrążony przez Teredinidae.

Opis:: This article presents the results of anatomical and growth ring analyses of Badenian fossil wood from the Roztocze region. All the wood specimens examined are classified as Taxodioxylon taxodii Goth. The growth rings of these woods are very narrow, and they vary considerably in width. Tracheids have large diameters and thin cell walls.The latewood zone is wide; the transition between early and latewood is gradual. Both false and wedge rings and also reaction wood zones are often found. These characteristics of the fossil wood make it a suitable aid to reconstructing the environmental conditions prevailing while the trees were alive. The environmental requirements of these ancient Roztocze trees are interpreted by comparison with those of their nearest living relatives, with the conclusion that they lived in waterlogged or temporarily flooded stands under seasonally changing environmental conditions and with a long growing season. The climate was warm and humid and characterized by significant variability, mainly as regards the amount of precipitation.

Opis:: The article describes twelve recorders excavated from archaeological sites dating back to the Mediaeval times and the Renaissance. Three of them are in the museums in Germany, two in the Netherlands and one in Estonia. Six are in Polish museum collections. The flutes from five locations (Puck, Nysa, Płock, Toruń and Warsaw) are described in this paper for the first time. All the instruments from the Polish territory have been accurately measured and identified for the kind of wood from which they were made. All the flutes were made from one piece of wood of the following tree genera: lilac (Nysa, Płock), plum (Dordrecht, Göttingen), cherry (Würzburg), maple (Elblag, Toruń, Tartu), boxwood (Esslingen, Amsterdam) and spruce (Puck, Warsaw). The oldest known recorders were primarily made of fruit tree wood (Würzburg, Dordrecht, Göttingen). Interesting was the use of spruce wood (softwood) for making aerophones, absent in the later preserved instruments of this type.

Opis:: The distribution of fossil wood genera has been demonstrated to be an effective proxy for Mesozoic terrestrial climates. In this study, we investigated the phytocoenoses, which were associated with Xenoxylon confirmed to be a marker for a cool and/or wet climate in a boreal hemisphere (i.e., Xenoxylon-phytocoenoses) during the Mesozoic, using specimens of fossil wood. It was confirmed that Xenoxylon co-occurs more often with some wood genera than with others. For example, Protocedroxylon, a wood that is most likely related to the Pinaceae, is the genus most often associated with Xenoxylon-phytocoenoses. Although Taxodioxylon is also found in Xenoxylon-phytocoenoses, it is not found, however, as consistently as Protocedroxylon. The distribution and diversity of Xenoxylon-phytocoenoses changed throughout the Mesozoic. During the Late Triassic and Late Cretaceous, Xenoxylon-phytocoenoses had low diversity and were restricted to higher palaeolatitudes during the Late Cretaceous. However, during the Early to Middle Jurassic, Xenoxylon-phytocoenoses were distributed much farther south, while their diversity concomitantly increased sharply. From the Late Jurassic to the Early Cretaceous, the distribution of Xenoxylon phytocoenoses moved northward in Europe and even more so in East Asia. The changes in the distribution of Xenoxylon-phytocoenoses are in agreement with changes in both global and regional climates. Our results also demonstrated that, within the Xenoxylon distribution range, the corresponding phytocoenoses were differentiated along a latitudinal gradient and according to the global climate change patterns during the Mesozoic.

Opis:: Aromatic hydrocarbons are present in the fossil wood samples in relatively small amounts. In almost all of the tested samples the dominating aromatic hydrocarbon is perylene and its methyl and dimethyl derivatives. The most important biomarkers present in the aromatic fraction are dehydroabietane, siomonellite and retene, compounds characteristic for conifers. The distribution of discussed compounds is highly variable due to such early diagenetic processes affecting the wood as oxidation and the activity of microorganisms. MPI1 parameter values (methylphenanthrene index) for the majority of the samples are in the range of 0.1 to 0.5, which results in the highly variable values of Rc (converted value of vitrinite reflectance) ranging from 0.45 to 0.70%. Such values suggest that MPI1 parameter is not useful as maturity parameter in case of Middle Jurassic ore-bearing clays, even if measured strictly on terrestrial organic matter (OM). As a result of weathering processes (oxidation) the distribution of aromatic hydrocarbons changes. In the oxidized samples the amount of aromatic hydrocarbons, both polycyclic as well as aromatic biomarkers decreases.

Opis:: Macroscopic observations, microscopic studies and literature data revealed that Middle Jurassic wood from Częstochowa area has a different state of preservation, and various types and degrees of mineralization and oxidation. Obtained results of organic matter fractionation illustrate a clear domination of polar fraction in the obtained extracts revealing low thermal maturity stage. Total organic carbon (TOC) values for analysed samples are in a wide range from 1.06% to 68.50%. The highest amount of TOC were measured in not or poorly mineralized wood samples but most of them are mineralized wood fragments, showing the TOC values in the range of 2% - 10%. Percentage content of carbonate in fossil wood constitute in a wide range from less than 1% CaCO3 to above 85% CaCO3. The resulting percentage of the total sulfur content is very varied and do not show convergence with other data such as TOC, carbonate content, etc and is most probable connected with pyritisation range. Unlike the Middle Jurassic clay samples, where long-chain and short-chain n-alkanes occur in similar concentrations, in wood samples always short-chain n-alkanes dominated, in the range from 15 to 23 carbon atoms in molecule. The values of the CPI are generally higher than 1 which indicates the contribution of organic matter derived from higher plant waxes, which are characteristic of e.g. needles from gymnosperm plants. Under the influence of postdiagenetic oxidation in mineralized wood samples distribution of n-alkanes is changing. Diaster-13(17)-enes with 28 and 29 carbon atoms in molecule are present in the wood samples, while those with 29 atoms strongly prevail.
Makroskopowe obserwacje, mikroskopowe badania i dane literaturowe wykazały, że środkowojurajskie drewno z okolic Częstochowy ma różny stan zachowania oraz różne rodzaje i stopień mineralizacji oraz utlenienia. Uzyskane wyniki rozdziału frakcyjnego pokazują wyraźną przewagę frakcji polarnej w badanych ekstraktach. Wartości TOC dla badanych próbek wahają się w szerokim zakresie od 1,06% do 68,50 %. Największa ilość TOC występuje w nie zmineralizowanych lub słabo zmineralizowanych próbkach drewna. Większość próbek to zmineralizowane fragmenty drewna, pokazując wartości TOC w zakresie od 2% - 10%. Zawartość procentowa węglanów w badanych próbkach znajduje się w szerokim zakresie od mniej niż 1% CaCO3 do ponad 85% CaCO3. Procentowa zawartość siarki całkowitej jest bardzo zróżnicowana i nie wykazuje zbieżności z innymi danymi, takimi jak TOC czy zawartość węglanów, itp. W odróżnieniu od środkowojurajskich iłów, gdzie długołańcuchowe i krótkołańcuchowe n-alkany występują w podobnych stężeniach , w próbkach drewna zawsze przewyższają n-alkanów krótkołańcuchowe, występujące w zakresie od 15 do 23 atomów węgla w cząsteczce. Wartości wskaźnika CPI są generalnie wyższe niż 1, co wskazuje na udział materii organicznej pochodzącej z wosków roślin wyższych. Pod wpływem post-diagenetycznego utleniania zmineralizowanych próbek drewna zmienia się dystrybucja n-alkanów. W badanych próbkach obecne są diaster-13 (17)-enes o 28 i 29 atomów węgla w cząsteczce, natomiast te o 29 atomów znacznie przeważają.

Opis:: This paper presents the results of analysis of the Miocene woods collected from three sampling sites in the Polish part of the Carpathian Foredeep. The location in the stratigraphic profile and the state of fossil preservation indicate that the woods were transported by waters flowing from highland or from mountainous regions and then deposited and fossilised in delta areas. Fragments of 16 lignified or silicified woods were collected for anatomical research. The fossil woods were classified as Piceoxylon piceae, Juniperoxylon pachyderma, Cupressinoxylon canadense and Cupressinoxylon polonicum. Disturbance zones observed in Cupressinoxylon polonicum are interpreted as frost rings. Frost rings suggest that despite the documented existence of warm and humid climatic conditions during the Miocene period, the temperatures in mountainous areas could temporarily drop below freezing point.

Opis:: The Błędów Desert is situated in the south of Poland. In this area, sand-gravel sediments predominate. The origin of the Błędów Desert is not associated with climatic conditions but with a strong development of excavation industry which started in the region in the Middle Ages. The surrounding forests became the main fuel source for the development of mining and metallurgical industry. Therefore, the area of the Błędów Desert was completely deforested. The paper presents reasons for the acceleration of biocenotical systems in the investigation area. For this purpose, transects representative for the following stages of plants successions: stage of encroachment plants, stage of sodding, stage of bushes (shrubs), stage of biogroup and stage of afforestation were made. Plant succession in the investigated transects developed in a multidirectional way. The ground for plants settling in the Błędów Desert represents fluvoiglacial, fluvial and aeolian sand with various grain sizes. Locally, in the old deflation fields, relict horizons of older podzolic and rust-coloured soil are the ground for the invading plants. The process of plant and soil succession takes place at the same time. Content of the available mineral elements in the initial horizons is different; it depends on the plant species in the places where these horizons developed.
