Histovariability and fossil diagenesis of Pissarrachampsa (Pseudosuchia, Notosuchia, Baurusuchidae) from the Upper Cretaceous of Southeast Brazil

open access: yesThe Anatomical Record, EarlyView.
Abstract Notosuchians were key components of western Gondwanan Cretaceous ecosystems in terrestrial predator niches and exhibited remarkable taxonomic and ecological diversity. Previous research has explored their physiology, metabolism, and histology, revealing varied growth patterns and life history strategies.

Divergent functional traits in three sympatric Arctic charr Salvelinus alpinus morphs are not coupled with the age of the lineage divergence [PDF]

open access: yes, 2016
Three genetically discrete morphs of Arctic charr in Loch Rannoch, Scotland originated from a recent divergence within the lake (in situ) (piscivore and benthivore morphs) and from secondary contact of two older lineages (ex situ; a planktivore–piscivore/

Description of the skull, braincase, and dentition of Moschognathus whaitsi (Dinocephalia, Tapinocephalia), and its palaeobiological and behavioral implications

open access: yesThe Anatomical Record, EarlyView.
Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

Computational fluid dynamics analysis of the upper airway after rapid maxillary expansion: a case report [PDF]

open access: yes, 2015
BACKGROUND: Assessment of the upper airway volume, morphology, and mechanics is of great importance for the orthodontic patient. We hypothesize that upper airway dimensions have significant effects on the dynamics of the airway flow and that both the ...

The revision of baphetids from the Middle Pennsylvanian of the Czech Republic: Morphology, ontogeny, palaeoecology, and the reassessment of the phylogeny of Baphetoidea

open access: yesThe Anatomical Record, EarlyView.
Abstract The baphetoids represent a clade of the Carboniferous stem‐tetrapods (Middle Mississippian—Middle Pennsylvanian) with a characteristic extension of the orbits into antorbital vacuities, which formed keyhole‐shaped openings on the skull. The more derived baphetids were crocodile‐like piscivores frequently occurring in coal‐bearing lacustrine ...
