Palynomorphs are one of the few groups fossils that provide biostratigraphic control in marine to nonmarine rocks and can be applied as proxies for paleoenvironmental paleoclimatic interpretations. Their utility is enhanced by their microscopic size, which usually less than 200 micrometres; they thus easily recovered from small rock samples. They occur throughout Phanerozoic therefore invaluabl...

Out of all extinct megafaunal mammals the Quaternary, cave bear Ursus spelaeus is one best represented in fossil record. This species has been found to exhibit skeletal morphological adaptations when exploiting varied environmental niches, be that spatially or temporally. Here, we employ geometric morphometrics and phenotypic trajectory analysis explore temporal changes across entire lower mola...

Integrated sequence stratigraphic and chemostratigraphic data yield a framework for correlations of stratigraphic units in the terminal Proterozoic to Cambrian Witvlei and Nama Groups of Namibia. Coupled with precise U-Pb zircon age constraints, these correlations make it possible to construct a composite reference section for use in calibrating terminal Proterozoic chronostratigraphy. The Nami...

The Caledonian basement crops out in the middle and southern part of Belgium two major tectonic units: Brabant Massif Parautochthon Stavelot-Venn, Rocroi, Givonne Serpont inliers Ardenne Allochthon. main aim this work is to achieve a chronostratigraphic correlation between inliers, from lower Cambrian Middle Ordovician. Throughout his career, Michel Vanguestaine established an informal acritarc...
