Integrating whole‐bone and regional analyses to understand human scapular growth
The Anatomical Record, EarlyView.Abstract This study investigates ontogenetic changes in human scapular morphology using three‐dimensional geometric morphometrics with whole‐bone and region‐specific analyses. The aim is to evaluate whether the scapula follows a regular developmental pattern and whether its functionally distinct components, the scapular spine (SS) and glenoid fossa ...

Eos, Transactions American Geophysical Union, 1983 The petrographic t se rm t o describe glassy volcanic rocks from the Bonin Islands in the Western Pacific has been around for nearly a century. Currently, however, “boninitic” has come to mean a process, and indeed boninites include a broad set of komatiite‐like rocks, which characterize Pacific Island arcs.

The Anatomical Record, EarlyView.Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Archaeology in Oceania, EarlyView.ABSTRACT Both the Tasmanian devil (Sarcophilus harrisii) and the Tasmanian tiger (Thylacinus cynocephalus) are believed to have become extinct on the Australian mainland about 3000 years ago. However, until now there were only 23 known rock art depictions of the Tasmanian devil and about 150 Tasmanian tiger paintings and petroglyphs, mostly at rock art
