The Permian ended with the largest of known mass extinctions in the history of life. This signal event has been difficult to recognize in Antarctic non-marine rocks, because the boundary with the Triassic is defined by marine fossils at a stratotype section in China. Late Permian leaves (Glossopteris) and roots Vertebraria), and Early Triassic leaves (Dicroidium) and vertebrates (Lystrosaurus) ...

Abstract We analyze the evolution of undeformed Middle to Late Pleistocene deposits Es Codolar (Southern Eivissa, Western Mediterranean). The outcrop records a succession characterized by alternation aeolian, colluvial and alluvial fan palaeosols that result in complex stratigraphic architecture. In this area, aeolian beds, are exposed along sea-cliffs for almost 500 m, allowing detailed descri...

Oxygen and hydrogen isotope composition of neoformed clay minerals is commonly used as a palaeoclimatic proxy. Usually, sediments rocks (including palaeosols) contain not only minerals, but also detrital and/or diagenetic ones. Together with the usually small size (micro- or nanometric) in these materials, this can generate difficulties during isotopic analyses by conventional spectrometry. To ...

Patterns of plant distribution by palaeoenvironment were examined across the Pennsylvanian-Permian transition in North-Central Texas. Stratigraphically recurrent packages of distinct lithofacies, representing different habitats, contain qualitatively and quantitatively different macrofloras and microfloras. The species pools demonstrate niche conservatism, remaining closely tied to specific hab...

Carbonate rhizoliths and related features are environmental ecological indicators of not only palaeosols, but also modern soils. They designate subaerial vadose pedogenic diagenesis environments. Rhizoliths commonly used as a tool for paleoenvironmental reconstructions, uncertainty remains regarding their formation mechanisms. Field characteristics the dune in Badain Jaran Desert, NW China were...
