Predicting ecology and hearing sensitivities in Parapontoporia—An extinct long‐snouted dolphin

open access: yesThe Anatomical Record, EarlyView.
Abstract Analyses of the cetacean (whale and dolphin) inner ear provide glimpses into the ecology and evolution of extinct and extant groups. The paleoecology of the long‐snouted odontocete (toothed whale) group, Parapontoporia, is primarily marine with its depositional context also suggesting freshwater tolerance.

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.
