Summary: This study provides a detailed description of the osteology and intraspecific variability of the limbs and girdles of early turtles (Proterochersis spp.), and compares them with other Triassic stem turtles. The results help us understand the diagnostic value of the early turtle appendicular skeleton and suggest that Proterochersis spp. may have been partly aquatic and could change their preferred habitat during ontogeny.

Summary: This study translated and adapted the Pelvic Girdle Questionnaire (PGQ) for Chinese patients, verifying the psychometric items' validation. The Chinese version of PGQ showed good construct validity and discriminative power for assessing the consequences of pelvic girdle pain among pregnant or postpartum Chinese women.

Summary: Discerning paleoclimate parameters in depositional systems of the continental interior is challenging, and often requires additional information or data sets. This study investigates the Los Rastros Formation in Argentina and uses carbon and oxygen stable isotopes to understand paleohydrological conditions and paleotemperatures. The results suggest that tectonic effects dominated over climate effects in hydrological fluctuations.

Summary: This study describes the osteological features and provides a complete reconstruction of the forelimb and hindlimb musculature of the Late Triassic sauropodomorph Thecodontosaurus antiquus. The results suggest that Thecodontosaurus was an agile biped, shedding light on the timing of important modifications in the appendicular musculature during the evolution of sauropodomorphs and their transition to quadrupedalism.

Summary: This study focuses on a high-resolution stratigraphic, sedimentologic, petrographic, and limnogeological investigation of the Agua de la Zorra depositional system to understand its evolution through space and time and to reconstruct the development of the carbonate factory within the palaeolake. The results strongly support volcanism and tectonics as the main allogenic factors controlling the Agua de La Zorra lacustrine system evolution.

Summary: This study reports a large marine reptile fossil from the Early Triassic of China, which demonstrates its affinity with the Omphalosauridae and reveals the unique feeding apparatus of these reptiles. The findings provide further evidence for an explosive radiation of marine reptiles in the Early Triassic and the rapid recovery of pelagic ecosystems after the Permo-Triassic mass extinction.

Summary: This study developed a consensus-based core outcome set for evaluating interventions in pregnancy-related and postpartum-related Pelvic Girdle Pain. The core outcome set includes five outcomes under the life impact domain, such as pain frequency, pain intensity/severity, function/disability/activity limitation, health-related quality of life, and fear avoidance. This set will ensure consistent reporting of meaningful outcomes and facilitate comparison and combination of findings from future studies in this area.

Summary: This study describes a new species of Probainognathia from the Norian period in Argentina, using high-resolution neutron and X-ray micro-tomography to analyze its unique characteristics. The researchers constructed a phylogenetic data matrix of non-mammalian cynodonts and conducted a paleobiogeographic analysis. The results indicate that Probainognathia and Mammaliamorpha originated in southwestern Gondwana, with the ancestral area of Mammaliaformes being the Lufeng Basin in China.

Self-administered tests combined with additional specific questions or a pain-drawing can be used as a screening tool to diagnose chronic PGP, but the modified SLR test has limitations.

Summary: Research into dicynodonts in the Chanarian Formation of South America has revealed taxonomic controversies, with different species being merged into one valid species in recent revisions. A new large dicynodont specimen from this formation shows distinct morphological features compared to known species from other regions. Furthermore, the discovery of new postcranial records expands the historical distribution of Stahleckeriinae in the Ischigualasto-Villa Uni ' on Basin.

Summary: Aetosaurs, quadrupedal archosaurs from the Late Triassic, are known for their small heads, long tails, and dorsal and ventral carapace formed by ornamented osteoderms. Research on Neoaetosauroides engaeus suggests that it had the ability to hunt small living prey or scavenge larger carcasses, expanding the potential ecological roles of aetosaurs. With a bite force comparable to that of Alligator mississippiensis, N. engaeus was likely a carnivorous or omnivorous species.

Summary: In this study, several isolated braincases of the iconic aetosaur Desmatosuchus from the Placerias Quarry locality in Arizona, United States were revised, figured, and redescribed. Two species of Desmatosuchus were identified at the Placerias Quarry, with distinct differences between D. spurensis and D. smalli. Through CT scan images, three new brain endocasts were developed, revealing unique features of each species and providing insights into their neurosensory capabilities. Additionally, the presence of an ossified orbitosphenoid on the anteriormost region of the braincase among aetosaurs was discussed.

Summary: This study presents a comparative osteological analysis of two lineages of Kannemeyeriiformes in the Chanares Formation in Argentina, focusing on the lower jaw of Dinodontosaurus brevirostris. The results confirm the phylogenetic relationship of D. brevirostris as the sister group of the Angonisaurus + Stahleckeriidae clade. The study also highlights the need for further research to better understand the evolutionary history of dicynodonts.

Summary: Rauisuchia is a group of quadrupedal and carnivorous pseudosuchians that lived worldwide during the Middle-Upper Triassic period. Fasolasuchus tenax from Argentina and Prestosuchus chiniquensis from Brazil are studied here. They have different bone compositions and growth rates, with F. tenax reaching maturity while P. chiniquensis being somatically immature. The overall rapid growth and high vascularisation seem to be common features in most rauisuchians.

Summary: Aetosauroides scagliai is one of the oldest members of the armored crocodile-line archosaurs, showing some predatory characteristics but likely being omnivorous. The discovery of its unique features suggests a greater trophic diversity in this clade than previously recognized, indicating the possibility of adaptations for herbivory early in their evolutionary history.

Summary: Aetosauria is a clade of armored pseudosuchians, with some of its oldest members found in Brazil. A comparative analysis of the axial skeleton of Aetosauroides and Polesinesuchus revealed differences in diagnostic features, suggesting that the latter may be a junior synonym of the former. This study indicates that morphological variation related to ontogeny impacts aetosaur taxonomy and phylogeny by reducing the number of putative 'dwarf' aetosaurs.

Summary: By studying the microstructure of postcranial bones of proterochampsids, researchers were able to infer the life-history traits dealing with growth dynamics, ontogenetic changes, dermal armor histogenesis, and lifestyle. The absence of an external fundamental system (EFS) and the developmental origin for the osteoderms were also observed. The growth patterns among proterochampsids exhibit some degree of variation even within a single species, possibly due to different causes such as phenotypic plasticity.
