Summary: The open-source programming language 'R' has become a standard tool in the palaeobiologist's toolkit, but there is a lack of agreed standards for data preparation and available frameworks to support such standards. To address this issue, the palaeoverse R package was developed, aiming to streamline data preparation and analyses, enhance code readability, and improve reproducibility of results.

Summary: This study investigates the accuracy of restoration of joint centre of rotation in the anteroposterior (AP) plane in uncemented total hip arthroplasty. The results show that most patients have a posterior displacement of the joint centre, which may affect the range of motion and muscle force.

Summary: Vertebrate-mediated seed dispersal is a common attribute of many plants, and the size and abundance of fleshy diaspores are influenced by regional climate and the nature of seed dispersers. The size distribution of fleshy diaspores is primarily constrained by physical or life-history limits and influenced by the expansion and evolution of seed plant populations.

Summary: The study revealed that modern giant clams grow faster than Holocene and Pleistocene specimens, possibly due to increased deposition of isotopically light nitrate aerosols in the modern era. Additionally, colder winter temperatures and past summer monsoons may have suppressed the growth of fossil giant clams. Giant clams can serve as sentinels of reef environmental change, indicating the health status of both individual clams and the reefs they inhabit.

Summary: In this paper, the discovery of several coleoid jaws in the lower Toarcian black shales along the Vilyui River (Yakutia, Russia) is described. It is the first time that a Lower Jurassic coleoid jaw has been recorded outside Europe, and the first report of such a finding from the Mesozoic in Siberia. The preservation and morphology of the described coleoid jaws are similar to the coeval jaws previously reported from Europe, which is made possible by the widespread occurrence of black shale facies associated with the early Toarcian oceanic anoxic event (TOAE) in Siberia.

Summary: Muaco and Taima-Taima sites in Venezuela are early human occupation sites in South America, with artifacts and preserved megafaunal remains dating back to 19,810-15,780 years ago. This study presents new visual and CT scanning analysis of glyptodont skulls from these sites, revealing intentional fractures in the fronto-parietal region caused by direct human percussion. The technique targeted areas of thinner cephalic shield for greater impact. These findings suggest human-glyptodont interaction during the Late Pleistocene, with an estimated 150-170 kg of potential food sources from an adult Glyptotherium cylindricum.

Summary: This study aimed to investigate the test-retest reliabilities of unconventional measures of quiet standing balance control in people with chronic stroke. The results showed that centre of pressure measures extracted from a single 30-second quiet standing trial may have sufficient reliability for some chronic stroke research studies, but clinical applications may require the average of at least two trials.

Summary: Conservation palaeobiology aims to understand the long-term dynamics of interactions between climate fluctuations, human activities, and biodiversity by studying geohistorical records. While case studies exist for vertebrates and plants, research on insects has been relatively neglected. This approach provides new opportunities for conservation biology by offering a millennial-scale perspective on biodiversity change.

Summary: This study describes the amber found in the dinosaur bonebed of Arino in Spain, revealing diverse biological inclusions and providing additional paleontological data. Arino is possibly the most prolific and diverse locality where fossiliferous amber and a dinosaur bonebed have been found in association, unlocking complete and reliable paleoecological data from the same site.

Summary: The study developed three robotic end-effectors for mechanical percussion in conjunction with a comprehensive telemedical diagnostic system. With 71.4% correctly classified samples, the ventral motorized device showed the best performance. The study demonstrates the feasibility of standardized mechanical percussion for telemedical execution, with the potential to improve diagnostic accuracy.

Summary: In this study, a 3D FEM of compound percussive system was used to simulate the dynamic single-cutter-rock interaction, and sensitivity analysis was conducted to investigate the effects of impact velocity, dynamic load amplitude, and torsional to axial impact frequency ratio on cutting force and penetration depth. The results showed that the cutting force increases first and then decreases rapidly with the increase in torsional impact velocity, and the penetration depth increases with dynamic load and impact velocity amplitudes. The study also found that stronger rock achieved higher penetration depth, and the penetration rate demonstrated improvement under both axial and torsional impacts.

Summary: This study explores the paleobiology of tube-dwelling worms, focusing on Selkirkia fossils from the Chengjiang Lagerstatte in China. The research reveals Selkirkia as a stem-group priapulid, capable of movement inside its protective tube. The presence of brachiopod epibionts suggests a potential ecological relationship and evolutionary significance of tube-dwelling in early Cambrian animals.

Summary: Extinction events in the geological past are similar to the present-day biodiversity crisis in that they produce dramatic changes in the spatial distributions of species. Reconstructing palaeobiogeographic patterns from fossils allows us to study the long-term processes governing the formation of regional biotas, but the extent to which biogeographic patterns can be preserved in the fossil record is not well understood.
