Journal of Anatomy, EarlyView.This study investigates the morphology and osteo‐histology of the wing skeleton of the world's first gliding reptiles, showing how it differs from those of extant gliding lizards, yet is also convergently similar. These findings pave the way for future biomechanical studies on the gliding locomotion of these emblematic fossil animals. Abstract The Late

Journal of Anatomy, EarlyView.A three‐dimensional biomechanical model of the musculoskeletal system is used to analyse the potential locomotor functions of the small (~1 kg) Late Triassic archosaurian reptile Gracilisuchus stipanicicorum. The study finds that, potentially like the ancestral archosaur, this taxon was probably quadrupedal, plantigrade and neither strongly sprawling ...

Divergent defense strategies and niche partitioning in Cretaceous micro‐beetles
Journal of Systematics and Evolution, EarlyView.We report a new clambid beetle from mid‐Cretaceous Kachin amber, Scutacalyptus kolibaci gen. et sp. nov., characterized by a flattened body and explanate margins. Alongside spiny and conglobating clambid forms, this diversity reflects niche partitioning and varied antipredator strategies in the Cretaceous forest floor.

Proměny přístupů studia neandertálců – s příkladem výzkumů v Portugalsku
AntropoWebzin, 2012 Neandetherthal skeletal remains are the first described and longest-studied modern human ancestors. The history of research on Neanderthals dates back to the discovery of the first specimen in the Feldhoffer cave in 1856. Initially, the debate focused on

Systematics and paleobiology of fossil Crustacea. Preface
Revista Mexicana de Ciencias Geológicas, 2018 In recent years, the number of conributions and specialists on fossil Crustacea has grown around the world. In 2000, the First Workshop on Mesozoic and Tertiary Decapod Crustaceans was held in Italy, with the participation of many specialists, mainly ...

Scientific ReportsThe origin and early diversification of ornithopods, a major clade of ornithischian dinosaurs, remain poorly understood, with conflicting phylogenetic hypotheses regarding rootward neornithischian relationships.

Terra Nova, EarlyView.ABSTRACT The early Miocene unconformity (EMU) formed during a transition in the tectonic regime of western North America that coincided with faunal diversification. The Railroad Canyon section in the northern Rocky Mountains provides a complete geologic record around this event. Our new magnetostratigraphic study in combination with published U‐Pb ages

Terra Nova, EarlyView.ABSTRACT The Carboniferous‐Permian Tarija basin of southern Bolivia evolved under major tectonic and climatic influence. The timing of transition from glacially influenced to arid conditions, after the Gondwanide tectonic event, has been based mainly on palynological correlations.

Expanding the Ichnofacies Model to Tidal Straits: Testing Predictions and Assessing Anomalies
Terra Nova, EarlyView.ABSTRACT Trace fossils are instrumental in facies analysis, but some depositional environments remain underexplored. Cenozoic deposits in Italy have been studied to evaluate the ichnology of tidal straits. These comprise four zones: (1) strait centre, (2) dune‐bedded strait zone, (3) strait end and (4) strait margin.
