Modified skulls but conservative brains? The palaeoneurology and endocranial anatomy of baryonychine dinosaurs (Theropoda: Spinosauridae) [PDF]
Journal of Anatomy, 2023 Spinosaurids were unusual large‐bodied tetanuran theropods with semi‐aquatic ecologies. The neuroanatomy of baryonychine spinosaurids has yet to be studied, and may inform about the early evolution of the spinosaurid brain and sensory capabilities. With unexceptional hearing and olfaction, baryonychine endocasts share morphological similarities with ...

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

Cranial Anatomy and Palaeoneurology of the Archosaur Riojasuchus tenuisceps from the Los Colorados Formation, La Rioja, Argentina [PDF]
PLoS ONE, 2016 Riojasuchus tenuisceps Bonaparte 1967 is currently known from four specimens, including two complete skulls, collected in the late 1960s from the upper levels of the Los Colorados Formation (Late Triassic), La Rioja, Argentina.

Morphometric analysis of lungfish endocasts elucidates early dipnoan palaeoneurological evolution [PDF]
eLife, 2022 The lobe-finned fish, lungfish (Dipnoi, Sarcoptergii), have persisted for ~400 million years from the Devonian Period to present day. The evolution of their dermal skull and dentition is relatively well understood, but this is not the case for the ...

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.

First palaeoneurological study of a sauropod dinosaur from France and its phylogenetic significance [PDF]
PeerJ, 2019 Despite continuous improvements, our knowledge of the palaeoneurology of sauropod dinosaurs is still deficient. This holds true even for Titanosauria, which is a particularly speciose clade of sauropods with representatives known from numerous Cretaceous

A new method for reconstructing brain morphology: applying the brain-neurocranial spatial relationship in an extant lungfish to a fossil endocast [PDF]
Royal Society Open Science, 2016 Lungfish first appeared in the geological record over 410 million years ago and are the closest living group of fish to the tetrapods. Palaeoneurological investigations into the group show that unlike numerous other fishes—but more similar to those in ...

The cranial endocast of Dipnorhynchus sussmilchi (Sarcopterygii: Dipnoi) and the interrelationships of stem-group lungfishes [PDF]
PeerJ, 2016 The first virtual cranial endocast of a lungfish from the Early Devonian, Dipnorhynchus sussmilchi, is described. Dipnorhynchus, only the fourth Devonian lungfish for which a near complete cranial endocast is known, is a key taxon for clarifying ...

Synchrotron scanning reveals the palaeoneurology of the head-butting Moschops capensis (Therapsida, Dinocephalia) [PDF]
PeerJ, 2017 Dinocephalian therapsids are renowned for their massive, pachyostotic and ornamented skulls adapted for head-to-head fighting during intraspecific combat.
