The cranial, mandibular, and hyoid anatomy of softshell turtles (Trionychidae): A revised character list for phylogenetic analysis

The Anatomical Record, EarlyView.
Abstract Softshell turtles (Pan‐Trionychidae) are an early branching clade of hidden‐necked turtles (Cryptodira) with a rich fossil record extending back to the Early Cretaceous. The evolutionary history of softshell turtles is still unresolved because of their conservative morphology combined with high levels of polymorphism related to morphological ...

Dental crown morphological variation and heterodonty in carcharhiniform sharks

The Anatomical Record, EarlyView.
Abstract Elasmobranch teeth are highly mineralized structures that constitute the majority of the fossil record for this group. Despite their taxonomic and evolutionary significance, detailed descriptions of dental morphology remain scarce. The order Carcharhiniformes, the most diverse among sharks, comprises 304 valid species that display remarkable ...

Osteohistology of two phorusrhacids reveals uninterrupted growth strategy

The Anatomical Record, EarlyView.
Abstract Phorusrhacidae were apex predators that primarily dominated South America ecosystems for at least 40 million years with their imposing size and predatory lifestyle—yet some aspects of their biology remain poorly understood. Osteohistology is a tool for understanding growth dynamics and biomechanical adaptations.

Zooarchaeological Analysis of an Atoll Assemblage From Central Micronesia

Archaeology in Oceania, EarlyView.
ABSTRACT There has been a dearth of archaeological research on atolls in the central‐eastern Caroline Islands of Micronesia. This has limited our understanding of pre‐contact subsistence and settlement strategies in these more marginal and remote environments, particularly in regards to zooarchaeological data.

Graman Revisited Once Again: A Reanalysis of the Late Holocene Legacy Faunal Assemblage From GB4 Rockshelter, New South Wales

Archaeology in Oceania, EarlyView.
ABSTRACT The archaeological site Graman B4 provided one of the first records of substantial dietary change in ancient Australian Aboriginal society. Initial examination of the faunal remains from this site suggested that Late Holocene hunters reduced their focus on high‐ranked kangaroos to increasingly rely on arboreal possums; and that these ...

Tracking the Dynamics of human Colonisation and Adaptation in Central Vanuatu: Preliminary Results From Excavation and Survey at Pangpang, East Efate

Archaeology in Oceania, EarlyView.
ABSTRACT In October 2022 an extensive archaeological landscape was identified by staff of the Vanuatu Cultural Centre at Pangpang on the east coast of Efate Island in central Vanuatu. It included midden deposits on the banks of the Pangpang River near the sea at Forari Bay where Lapita and Early Erueti‐style pottery sherds were recovered.

Augmented reality for teaching undergraduate human anatomy: An educators' perspective

Anatomical Sciences Education, EarlyView.
Abstract The purpose of this study was to explore the perspectives of Australian educators on using augmented reality (AR) as a method for learning human anatomy in the undergraduate health sciences. This will determine the current value of AR and guide future research and development. This prospective qualitative study used a mixed‐methods approach to

Developing medication independence: The experience of UK teenagers

British Journal of Clinical Pharmacology, EarlyView.
Aims There is a progression through childhood from being provided medications by caregivers to having to take responsibility for medications yourself, but little is known about when the transition of adolescents managing medicines begins. The aim of this study was to obtain a cross‐sectional sample of UK adolescents and when they become independent ...

Prediction and Experimental Validation of the Influence of T-Stress on I–II Mixed-Mode Fracture in Rock

Advances in Civil Engineering
Traditional fracture criteria only consider the singular terms in the Williams expansion and neglect higher-order term coefficients, resulting in significant discrepancies between predicted and measured values.
