Abstract:
... The Early Pennsylvanian Xiaheyan entomofauna (Ningxia, China) is among the earliest assemblages of winged insects known so far, and therefore provides an essential input on deciphering the early diversification of this group. Despite its evolutionary significance, both the age and depositional environment remained poorly constrained. Here, we present high-resolution documentation of litho- and bio ...

Abstract:
... Variations of trace element (e.g. Mg, Sr, Ba, Fe, Zn etc.) concentrations along a speleothem's growth axis constitute important paleoclimate proxies. The use of laboratory micro X-ray fluorescence spectrometry as a fast and cheap alternative for conventional mass spectrometry techniques for trace element analysis on speleothems has been explored in the past and yielded satisfactory results. Howeve ...

Abstract:
... Amber samples with bivalve borings from six localities around the world, ranging in age from Hauterivian to Miocene, have been studied. The possible assignment to Teredolites or Gastrochaenolites is discussed considering the type of substrate as an ichnotaxobase. It is proposed to regard amber or similar resins as a variant of xylic substrates and to maintain the separation between the two ichnoge ...

Abstract:
... Fossils in the immediate aftermath of mass extinctions are often of small size, a phenomenon attributed to the Lilliput Effect (temporary, size reduction of surviving species). There has been little attempt to study size trends during subsequent recovery intervals nor has the relationship between size, diversity and environmental controls been evaluated. Here we examine the recovery following the ...

Abstract:
... Magnetic parameters are widely used in the loess-palaeosol sequence tracing Quaternary climate change on the Chinese Loess Plateau (CLP). However, the climatic implication and magnetic enhancement mechanism in aeolian Red Clay on the CLP is still debated. Chlorite is a common Fe-bearing silicate in Red Clay and it is easily to be weathered. The transformation of weakly magnetic ferrihydrite, a pro ...

Abstract:
... Records of Australian climate during Marine Isotope Stages 5 and 7 (130–71 and 243–191 ka) are rare, preventing detailed assessments of long-term climate, drivers and ecological responses across the continent over glacial-interglacial timescales. This study presents a geochemistry-based palaeoclimate record from Fern Gully Lagoon on North Stradbroke Island (also known as Minjerribah) in subtropica ...

These three methods allow both short- and long-term diets to be distinguished. As microwear analysis shows a negative correlation between the numbers of pits and scratches counted, the proportions of pits/(pits + scratches) were used fo ...

Vast ice sheets of at least two global glaciations, the Sturtian (~720–660 Ma) and Marinoan (<654–635 Ma), advanced to sea level at low latitudes, a scenario that is at the heart of the general Snowball Earth hypothesis. This hypothesis is supported by results of recent work in geochr ...
