The morphology of the oval window in Paranthropus robustus compared to humans and other modern primates

open access: yesThe Anatomical Record, EarlyView.
Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

A proximodistal gradient in bone structure and mechanics in the wings of Seba's short‐tailed bat, Carollia perspicillata

open access: yesThe Anatomical Record, EarlyView.
Abstract Bats possess the remarkable ability to fly, and with this, distinctive wing bone properties. We investigated the structural, mechanical, and compositional properties of the humerus, radius, metacarpals, and proximal and middle phalanges of Carollia perspicillata, an approximately 15 g fruit‐eating bat native to the Neotropics.

Understanding the first measurement of B(B→Kνν¯)

open access: yesPhysics Letters B
Recently, Belle II reported on the first measurement of B(B±→K±νν¯) which appears to be almost 3σ larger than predicted in the Standard Model. We point out the important correlation with B(B→K⁎νν¯) so that the measurement of that decay mode could help ...

Intraspecific variation of cochlear morphology in bowhead and beluga whales

open access: yesThe Anatomical Record, EarlyView.
Abstract The bony labyrinth of the petrosal bone, a distinctive feature of mammal skulls, is often identified in micro‐computed tomography imaging to infer species' physiological and ecological traits. When done as part of a comparative study, one individual specimen is normally considered representative of a species, and intraspecific variation is ...
