XRONOS: An Open Data Infrastructure for Archaeological Chronology

Journal of Computer Applications in Archaeology
XRONOS (https://xronos.ch) is an open data infrastructure for the backbone of the archaeological record – chronology. It provides open access to published radiocarbon dates and other chronometric data from any period, anywhere in the world.

Developmental differences in cortical bone structure in chimpanzee and human femora reflect early locomotor independence in humans

The Anatomical Record, EarlyView.
Abstract The cortical bone structure of long bone diaphyses changes throughout growth via skeletal modeling and has important implications for bone strength and structural integrity. Ontogenetic trends in diaphyseal structure have been identified in both chimpanzees and humans but it is not yet clear how these trends compare given notable differences ...

Tracheal chambers as a key innovation for high‐frequency emission in bat echolocation

The Anatomical Record, EarlyView.
Abstract Key innovations are pivotal for biodiversity and facilitating evolutionary success, enabling organisms' adaptation to various ecological niches through the diversification of phenotypic traits. In mammals, notable adaptations include evolving hypsodonty for grazing on grasses and, for bats, evolving echolocation and wing acquisition.

Pike Use in Megafauna Hunting and Antipredator Defense: Historical Techniques and Paleolithic Research

Quaternary
This paper presents a comprehensive assessment of megafauna confrontation using pikes, as recorded in historical accounts and ethnographic studies depicting techniques of hunter-gatherers, pastoralists, colonial hunters and others. In contrast to the two

Alloy ratio and raw material sourcing of Warring States Period bronze bracelets in Huili County, Southwest China by pXRF and MC-ICP-MS

Heritage Science, 2020
Up to now, there have been few monographic analyses of metal ornaments in China. This study presents a case study of the metallurgical archaeology on bracelets from Huili (会理), which may shed light on the issue as production status, technical level, use ...

Three‐dimensional digital analysis of musteloid masticatory muscle architecture

The Anatomical Record, EarlyView.
Musteloids span an enormous breadth of dietary modes within a single superfamily. In this study, we utilize digital dissection techniques to reconstruct the internal 3D anatomy of muscles within the musteloid feeding apparatus, and explore how dietary specializations might alter the size, orientation, and curvature of fascicles therein.

Deeply divergent archaic mitochondrial genome provides lower time boundary for African gene flow into Neanderthals

Nature Communications, 2017
Ancient DNA keeps expanding our understanding of complex genetic relationships between Pleistocene hominins. Here, Posth and colleagues analyse the mitochondrial genome of an archaic human that diverged from other Neanderthals ∼270,000 years ago ...

Pelvic breadth and juvenile locomotor energetics: Implications for the obstetrical dilemma hypothesis across human growth in past and present humans

The Anatomical Record, EarlyView.
Abstract The obstetrical dilemma hypothesis (ODH) proposes an evolutionary trade‐off between obstetric requirements and locomotor performance. However, whether external pelvic breadth measures influence walking energetics during human growth remains poorly understood.
