Modified skulls but conservative brains? The palaeoneurology and endocranial anatomy of baryonychine dinosaurs (Theropoda: Spinosauridae). [PDF]

J Anat, 2023
AbstractThe digital reconstruction of neurocranial endocasts has elucidated the gross brain structure and potential ecological attributes of many fossil taxa, including Irritator, a spinosaurine spinosaurid from the “mid” Cretaceous (Aptian) of Brazil.

The palaeoneurology of a new specimen of the Middle Triassic dicynodont synapsid Kombuisia frerensis

Acta Palaeontologica Polonica
The pineal eye is a photoreceptive organ, sometimes called the “third eye”, housed within the parietal foramen of some ectothermic vertebrates (Eakin 1973; Quay 1979).

Neuroanatomy of the mekosuchine crocodylian Trilophosuchus rackhami Willis, 1993. [PDF]

J Anat, 2022
This study described the neuroanatomy of the mekosuchine crocodylian Trilophosuchus rackhami from the Middle Miocene of Australia. Although the neuromorphology of Trilophosuchus rackhami follows the general patterns seen in crocodylomorphs, it is nevertheless characterized by a unique combination of features that stand out among currently known taxa ...

Icex: Advances in the automatic extraction and volume calculation of cranial cavities. [PDF]

J Anat, 2023
Icex is a new R tool for the study of cranial cavities. It is tested here to automatically assess the size and shape of different cranial cavities on an ontogenetic sample of modern humans, three fossil hominins, and three species of non‐human primates.

Dinosaur palaeoneurology: an evolving science. [PDF]

Biol Lett
Our fascination with dinosaur brains and their capabilities essentially began with the first dinosaur discovery. The history of this study is a useful reflection of palaeoneurology as a whole and its relationship to a more inclusive evolutionary neuroscience.

What do brain endocasts tell us? A comparative analysis of the accuracy of sulcal identification by experts and perspectives in palaeoanthropology. [PDF]

J Anat
Palaeoneurology is a complex field as the object of study, the brain, does not fossilize. We asked 14 experts to manually identify foldings in a proxy endocast obtained from an MRI of an actual in vivo Homo sapiens. Researchers can perceive sulcal imprints with reasonably high accuracy, but their correct identification and labelling remains a challenge,

Palaeoneurological clues to the evolution of defining mammalian soft tissue traits. [PDF]

Sci Rep, 2016
AbstractA rich fossil record chronicles the distant origins of mammals, but the evolution of defining soft tissue characters of extant mammals, such as mammary glands and hairs is difficult to interpret because soft tissue does not readily fossilize. As many soft tissue features are derived from dermic structures, their evolution is linked to that of ...

Avian palaeoneurology: Reflections on the eve of its 200th anniversary [PDF]

Journal of Anatomy, 2020
AbstractIn birds, the brain (especially the telencephalon) is remarkably developed, both in relative volume and complexity. Unlike in most early‐branching sauropsids, the adults of birds and other archosaurs have a well‐ossified neurocranium. In contrast to the situation in most of their reptilian relatives but similar to what can be seen in mammals ...

Palaeoneurology and the Emergence of Language [PDF]

Bulletins et Mémoires de la Société d'Anthropologie de Paris, 2020
The origin of language has been much debated over the years. Recent research has centred the controversies on two main ideas. Language, as defined by the Basic Property formulated by Chomsky, is a characteristic unique to Homo sapiens that developed in our species in the past 300,000 years.

Neurosensory anatomy and function in Seymouria

Journal of Morphology, Volume 284, Issue 5, May 2023., 2023
We reconstruct the first virtual cranial endocast and the first complete otic endocasts of Seymouria, revealing no indication of the increased encephalization or braincase ossification typical of more derived crown amniotes. Our results clarify the plesiomorphic condition for carotid innervation in amniotes, with Seymouria showing a similar condition ...
