Zoophycos
Opis:: The trace fossil Zoophycos has been first time recognized in the Sudetes within the lower Carboniferous (upper Visean, crenistria Zone) of the Paprotnia Beds in the Bardo Unit. A distinct concentration of Zoophycos occurs in the lower part of the Paprotnia profile, in mudstones interbedded with bentonites, which were most likely deposited between storm wave base and fair weather wave base, in oxygenated water.

Opis:: In this paper the trace fossil associations and the taphocoenoses from the Upper Visean Paprotnia Beds (Bardo Unit) have been compared. Eleven ichnogenera have been recognized (Zoophycos, Chondrites, Protovirgularia, Lockeia, Palaeophycus, Nereites, Planolites, Altichnus, Paleobuprestis, cf. Thalassinoides and ?daedaloid form). A new ichnospecies Paleobuprestis sudeticus has been defined herein. It is the oldest wood-boring trace fossil observed in macroscale and the first wood-boring trace fossil preserved on the archaeocalamites stems. Based on ichnodiversity and relative abundance of trace fossils in the investigated strata three ichnoassociations have been distinguished: Zoophycos–Chondrites–Palaeophycus, Palaeophycus–Nereites and Paleobuprestis. Vertical succession of both the taphocoenoses and ichnoassociations reflects the different colonization stages of the substrate and is linked to bathymetric changes in the marine basin from offshore to nearshore conditions in warm climate at low latitude. The Paprotnia profile is a unique record of the Asbian–Brigantian transition.

Tytuł:: Palynology of the upper Visean Paprotnia Beds (Bardo Unit, Polish Sudetes)

Opis:: The siliciclastic rocks of the Paprotnia Beds from the Bardo Unit (Polish Sudetes) provide abundant and diverse palynological material. The miospore assemblages recovered allow distinction of two miospore biozones. The Tripartites vetustus–Rotaspora fracta (VF) Biozone was recognized in the lower and the middle parts of the section. In its upper part the Cingulizonates capistratus (Cc) Subbiozone, the lower part of the Cingulizonates capistratus–Bellispores nitidus (CN) Biozone was distinguished. These results indicate that the rocks of the Paprotnia section, considered earlier on the basis of biostratigraphic and radiometric data as upper Asbian, should be assigned to the upper Asbian and Brigantian. The location of the Asbian/Brigantian boundary and the possible occurrence of a gap in the Brigantian part of the section are discussed. Palynofacies observations of miospore preservation and frequency provided additional information, which confirm the gradual shallowing of the environment of deposition from offshore to onshore. Thermal maturity assessment of organic matter, based on miospore colour, indicates early mature and mature stages of organic matter thermal alteration.

Tytuł:: A new species of Lambdarina (Rhynchonellida, Brachiopoda) from the Viséan of central Sudetes (Poland) and its phylogenetic position

Opis:: A new species of micromorphic articulate brachiopod (Rhynchonellida) Lambdarina jugowiensis sp. nov., from the upper Viséan (Sokolec Beds) of central Sudetes, SW Poland, is described. The studied specimens are calcified, what makes them unique in respect of their state of preservation. The material is represented by a full range of growth stages; from brephic to gerontic. Based on its morphological features and the palaeogeographical distribution of all its known species, two main evolutionary lines are proposed for the genus; the Australian and the European ones. Lambdarina was widely distributed in the equatorial-tropical waters of marginal seas of the Palaeotethys Ocean, mostly during Mississippian time.
