Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage. [PDF]
Anat Rec (Hoboken)Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.

The endocranial anatomy of the stem turtle Naomichelys speciosa from the Early Cretaceous of North America [PDF]
Acta Palaeontologica Polonica, 2019 Fossil turtles are one of the least studied clades in regard to endocranial anatomy. Recently, the use of non-invasive technologies, such as radiographic computed tomography (CT), increased the knowledge of the neuroanatomy of several extinct and extant ...

Are endocasts good proxies for brain size and shape in archosaurs throughout ontogeny? [PDF]
J Anat, 2019 Abstract Cranial endocasts, or the internal molds of the braincase, are a crucial correlate for investigating the neuroanatomy of extinct vertebrates and tracking brain evolution through deep time. Nevertheless, the validity of such studies pivots on the reliability of endocasts as a proxy for brain morphology. Here, we employ micro‐computed tomography

But how does it smell? An investigation of olfactory bulb size among living and fossil primates and other euarchontoglirans. [PDF]
Anat Rec (Hoboken)Analysis of cranial endocast data of 181 extant and 41 fossil species from Euarchontoglires shows that there was a reduction in olfactory bulb size in Crown Primates, but that there were also subsequent reductions in various other primate clades (Anthropoidea, Catarrhini, Platyrrhini, crown Cercopithecoidea, Hominoidea).

American Journal of Biological Anthropology, Volume 182, Issue 3, Page 412-427, November 2023., 2023 Abstract Objectives The diploic venous system has been hypothesized to be related to human brain evolution, though its evolutionary trajectory and physiological functions remain largely unclear. This study examines the characteristics of the diploic venous channels (DCs) in a selection of well‐preserved Homo neanderthalensis and Upper Paleolithic Homo ...

American Journal of Biological Anthropology, Volume 180, Issue 4, Page 768-776, April 2023., 2023 Abstract Objectives Two decades ago, Rilling and Seligman, hereafter abbreviated to RAS Study, suggested modern humans had relatively larger temporal lobes for brain size compared to other anthropoids. Despite many subsequent studies drawing conclusions about the evolutionary implications for the emergence of unique cerebral specializations in Homo ...

Neuroanatomy of the mekosuchine crocodylian Trilophosuchus rackhami Willis, 1993
Journal of Anatomy, Volume 241, Issue 4, Page 981-1013, October 2022., 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 ...

Paleoneuroanatomy of the European lambeosaurine dinosaur Arenysaurus ardevoli [PDF]
PeerJ, 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.

Diversity, 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.
