: Scales of a new thelodont species, Amaltheolepis terranovi sp. nov., are described from the upper Emsian, Lower Devonian Shevchenkinskaya Formation of Novaya Zemlya, Arctic Russia. The new species shows strong resemblance with the Emsian “Verdalen assemblage” from Spitsbergen, supporting an Emsian age for the upper part of the Shevchenkinskaya Formation. This conclusion in the context of the various Amaltheolepis assemblages from Spitsbergen, allows for a more accurate comparison and correlation between assemblages from different regions in the Northern Hemisphere, suggesting that the type species, Amaltheolepis winsnesi from Spitsbergen, is Eifelian in age.

: This paper presents a proof of concept in the study of human respiratory motion from a palaeoanthropological approach. The hybrid methodology proposed merges Motion Capture techniques (optoelectronic plethysmography) with 3D geometric morphometrics of the superior torso surface during incremental running exercise. Results reveal the importance of the expiratory phase during high-intensity exercise breathing and arouse a discussion about the structure and function of the respiratory system in human evolution.

: The origin and function of peculiar mushroom-shaped cuticular structures in some decapod crustaceans remains unknown. This ornamentation has appeared several times in widely disparate clades (in podotreme and heterotreme crabs, and pagurids). These structures are analysed in the modern genus Daira and compared with fossil material from the Eocene of Huesca and the Miocene of Alicante and Mallorca. A morphological and petrographic study is carried out using conventional microscopy and Scanning Electron Microscopy to understand the microstructure in modern and fossil representatives. This provides a clear view of the mushroom-like structures that cover the carapace of Daira and the distribution of the diff erent layers of the exoskeleton. The results reveal a complex morphology, which involves all layers of the cuticle, with changes in the thickness of the exocuticle in diff erent areas, and the presence of conical structures that especially aff ect the outer layers. These convolutions form a network of channels connected to the outside
