Cranial Material of Long-Snouted Dolphins (Cetacea, Odontoceti, Eurhinodelphinidae) from the Early Miocene of Rosignano Monferrato, Piedmont (NW Italy): Anatomy, Paleoneurology, Phylogenetic Relationships and Paleobiogeography

open access: yesDiversity, 2023
We provide a new study of previously published eurhinodelphinid materials from the early Miocene of Piedmont (NW Italy) based on a new preparation of the fossil specimens. We studied specimens previously assigned to Tursiops miocaenus and Dalpiazella sp.

Braincase anatomy of the Paleocene crocodyliform Rhabdognathus revealed through high resolution computed tomography [PDF]

open access: yesPeerJ, 2021
Dyrosaurids were highly specialized, largely marine, relatives of living crocodylians, and one of the few archosaur lineages to survive the K-Pg extinction.

Paleoneuroanatomy of the European lambeosaurine dinosaur Arenysaurus ardevoli [PDF]

open access: yesPeerJ, 2015
The neuroanatomy of hadrosaurid dinosaurs is well known from North America and Asia. In Europe only a few cranial remains have been recovered that include the braincase.

From Smart Apes to Human Brain Boxes. A Uniquely Derived Brain Shape in Late Hominins Clade

open access: yesFrontiers in Earth Science, 2020
Modern humans have larger and more globular brains when compared to other primates. Such anatomical features are further reflected in the possession of a moderately asymmetrical brain with the two hemispheres apparently rotated counterclockwise and slid ...

A fresh look at Cladarosymblema narrienense, a tetrapodomorph fish (Sarcopterygii: Megalichthyidae) from the Carboniferous of Australia, illuminated via X-ray tomography [PDF]

open access: yesPeerJ, 2021
Background The megalichthyids are one of several clades of extinct tetrapodomorph fish that lived throughout the Devonian–Permian periods. They are advanced “osteolepidid-grade” fishes that lived in freshwater swamp and lake environments, with some taxa ...

The first virtual cranial endocast of a lungfish (sarcopterygii: dipnoi).

open access: yesPLoS ONE, 2014
Lungfish, or dipnoans, have a history spanning over 400 million years and are the closest living sister taxon to the tetrapods. Most Devonian lungfish had heavily ossified endoskeletons, whereas most Mesozoic and Cenozoic lungfish had largely ...

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

open access: yesVeterinární 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

Digital Endocasting in Comparative Canine Brain Morphology

open access: yesFrontiers in Veterinary Science, 2020
Computed tomography (CT) is one of the most useful techniques for digitizing bone structures and making endocranial models from the neurocranium. The resulting digital endocasts reflect the morphology of the brain and the associated structures. Our first

Paleoneuroanatomy of the aetosaur Neoaetosauroides engaeus (Archosauria: Pseudosuchia) and its paleobiological implications among archosauriforms [PDF]

open access: yesPeerJ, 2018
The paleoneuroanatomy of pseudosuchian archosaurs is poorly known, based on direct examination of the internal morphology of braincases and a few artificial endocasts.

Beyond Endocasts: Using Predicted Brain-Structure Volumes of Extinct Birds to Assess Neuroanatomical and Behavioral Inferences

open access: yesDiversity, 2020
The shape of the brain influences skull morphology in birds, and both traits are driven by phylogenetic and functional constraints. Studies on avian cranial and neuroanatomical evolution are strengthened by data on extinct birds, but complete, 3D ...
