"The repeated emergence of similar morphologies in the dental elements of Permian Sweetognathus conodonts has been a hypothesized example of parallel evolution. To test if morphological parallelisms occur between isolated Sweetognathus lineages, this study uses two-dimensional-based geometric morph...
"Organismic groups vary non‐randomly in their vulnerability to extinction. However, it is unclear whether the same groups are consistently vulnerable, regardless of the dominant extinction drivers, or whether certain drivers have their own distinctive and predictable victims. ... Focusing on the fo...
"The Palaeozoic record of chondrichthyans (sharks, rays, chimaeras, extinct relatives) and thus our knowledge of their anatomy and functional morphology is poor because of their predominantly cartilaginous skeletons. Here, we report a previously undescribed symmoriiform shark, Ferromirum oukherbouc...
"The role of minerals in Burgess Shale–type fossilization is controversial, particularly that of the clay mineral kaolinite. Kaolinite may have formed on carcasses or attached to them as they decayed, stabilizing organic matter. Alternatively, kaolinite may have formed during metamorphism, playing ...
"The rhodolith-forming coralline red algal species Lithothamnion glaciale is the key ecosystem engineer of rhodolith beds on the coast of Svalbard. Because it significantly increases local biodiversity in this high-Arctic environment, we investigate the potential impact of changing environmental pa...
"The Guanling Formation (Middle Triassic, Anisian-Ladinian) of Yunnan Province in southwestern China reveals traces of marine tetrapods.Tracks and trackways have now been discovered near the city of Anshun in Guizhou Province, in slightly older strata and unique features allow to assign this morpho...
"This is the first special issue of Geoconservation Research, focussing on ‘Geoconservation in the Carpathian area’. The aim in this volume was to select a geographic region that spans several nations, and to explore common issues. Although connected by natural assets, mainly the Carpathian Mountai...
"Scanning electron microscope (SEM) imaging of fossils allows unlocking ultrastructural information about their skeletal tissues, but sample preparation of biominerals forming their skeletons requires time, patience, and knowledge. SEM and associated analytical methods allow the observation of inte...
"The PTME was followed by a long period of recovery revolutionizing marine and terrestrial ecosystems. New clades emerged including decapods and marine reptiles in the oceans and new tetrapods on land. The authors present a review of Early Triassic terrestrial tetrapod faunas, geological formations...
"Reconstructing geographic range sizes from fossil data is a crucial tool in paleoecology, elucidating macroecological and macroevolutionary processes. Studies examining links between range size and extinction risk may also offer a predictive tool for identifying species most vulnerable in the “six...
