A Tale of Two Tails: Untangling the Phylogeography and Demographic History of Extant Species of Mulgara (Dasycercus spp.) in the Australian Arid Zone

open access: yesJournal of Biogeography, EarlyView.
ABSTRACT Aim Australia's arid and semi‐arid zones cover about 70% of the continent, yet our understanding of the biogeography of these diverse and expansive landscapes remains limited. Mulgara (Dasycercus spp.; Marsupialia: Dasyuridae), a widely distributed mammal taxon, offers an opportunity to explore patterns of the population structure across the ...

Potential metabolic records in isotope signals of chondrichthyan hard tissues

open access: yesJournal of Fish Biology, EarlyView.
Abstract Recent advances have demonstrated that the field metabolic rates (FMRs) of teleost fishes can be quantified from stable isotope compositions of carbonate‐biomineralized otoliths. Bones and teeth, in addition to bioapatite, contain carbonate and should retain a similar isotopic expression of metabolic rate.

Bipedalism or bipedalisms: The os coxae of StW 573

open access: yesJournal of Anatomy, EarlyView.
There has been a long debate about the possibility of multiple contemporaneous species of Australopithecus in both eastern and southern Africa, potentially exhibiting different forms of bipedal locomotion. Here, we describe the previously unreported morphology of the os coxae in the 3.67 Ma Australopithecus prometheus StW 573 from Sterkfontein Member 2

Microstructure and development of the dermal ossicles of Antarctopelta oliveroi (Dinosauria, Ankylosauria): A complex morphogenetic system deciphered through three‐dimensional X‐ray microtomography

open access: yesJournal of Anatomy, EarlyView.
Series of images of the dermal ossicle of Antarctopelta oliveroi (Dinosauria, Ankylosauria) illustrating (A) the 3D distribution of the vascular mesh in the ossicle; (B) the large volume of the numerous cells in periphery; (C) the radial orientation of the fiber bundles in the main core of the osteoderm (called basal plate); (D) the orthogonal ...
