Brain size reduction in dogs was already established at least by the Late Neolithic of Western Europe, 5000 years ago [PDF]

Royal Society Open Science
The timing and causes of brain size reduction in domestic dogs remain uncertain. Using endocast volume as a proxy for brain size, this study provides a first insight into long-term brain size evolution in the wolf-dog lineage.

Macroscopic distribution of the renal artery and intrarenal arteries in mole rats (Spalax leucodon)

Veterinární Medicína, 2014
A study was conducted of the kidneys of adult mole rats (Spalax leucodon) to describe the macro- and mesoscopic morphology of the renal arterial distribution and some additional anatomical features. The kidneys of the mole rat lay alongside the vertebral

Palaeoecological inferences for the fossil Australian snakes Yurlunggur and Wonambi (Serpentes, Madtsoiidae) [PDF]

Royal Society Open Science, 2018
Madtsoiids are among the most basal snakes, with a fossil record dating back to the Upper Cretaceous (Cenomanian). Most representatives went extinct by the end of the Eocene, but some survived in Australia until the Late Cenozoic.

New techniques for old bones: Morphometric and diffeomorphometric analysis of the bony labyrinth of the Reilingen and Ehringsdorf Neandertals

The Anatomical Record, EarlyView.
Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

Morphology and morphometry of the inner ear of the dromedary camel and their influence on the efficiency of hearing and equilibrium

Zoological Letters, 2022
Background The inner ear morphology and size are linked to hearing and balance ability. The goal of this study was to determine the morphology and morphometrics of the dromedary camel's inner ear and how it influences hearing accommodation and ...

Nasal soft‐tissue anatomy of Triceratops and other horned dinosaurs

The Anatomical Record, EarlyView.
Abstract Although ceratopsid dinosaurs possess a characteristically hypertrophied narial region, soft‐tissue anatomy associated with such a skeletal structure and their biological significance remain poorly understood. The present study provides the first comprehensive hypothesis on the soft‐tissue anatomy in the ceratopsid rostrum based on the Extant ...

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

The Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,
