A large collection of the trace fossil Rhizocorallium from Middle Triassic Polish part Germanic Basin (Peri-Tethys) is analysed and their ichnotaxonomical classification presented. Special attention given to deep form with a vertical retrusive spreite, filled faecal pellets, detailed documentation this structure, based on isolated specimens serial sections. This analysis also reveals ∩-shaped d...
A new trace fossil, Koptichnus rasmussenae, was recently reported from the Cretaceous of Denmark. This burrow is thickly lined with cuboids that tracemaker cut siliceous sponges. newly discovered specimen lower Selandian Kerteminde Marl, found in a loose boulder Gundstrup gravel pit (Fyn, Denmark), extends stratigraphical range this ichnotaxon previously known Coniacian to middle Paleocene and ...
[1] Data obtained during the TRACE-P experiment is used to evaluate how well the CFORS/STEM-2K1 regional-scale chemical transport model is able to represent the aircraft observations. Thirty-one calculated trace gas and aerosol parameters are presented and compared to the in situ data. The regional model is shown to accurately predict many of the important features observed. The mean values of ...
Remote sensing of light-absorbing particles (LAPs), or dark colored impurities, such as black carbon (BC) and dust on snow, is a key remaining challenge in cryospheric surface characterization and application to snow, ice, and climate models. We present a quantitative data set of in situ snow reflectance, measured and modeled albedo, and BC and trace element concentrations from clean to heavily...
A new ichnospecies Mammillichnis monstrum isp. nov. (Domichnia) is described from turbidite sandstone in the upper part of Mospyne Formation (late Bashkirian, Early Pennsylvanian) southern Luhansk Oblast, eastern Ukraine. represented by hypichnial, hemispherical, slightly flattened passive fillings a large burrow; apex burrow casts has concentric depression or small rounded tubercle. differs ag...
