Sulci 3D mapping from human cranial endocasts: A powerful tool to study hominin brain evolution. [PDF]
Hum Brain Mapp, 2022 Three‐dimensional density maps as an innovative tool for studying cranial endocasts. This tool provides new insights into visualising inter‐individual sulcal imprint variation on extant human endocasts. This study will contribute immensely to solving key questions in paleoneurology.

Are endocasts reliable proxies for brains? A 3D quantitative comparison of the extant human brain and endocast. [PDF]
J Anat, 2021 Is the endocast a reliable proxy for reconstructing the brain of fossil specimens? By quantitatively comparing extant human brains and endocasts using MRIs and CT‐scans, here we address this fundamental question and support the significance of fossil endocasts in paleoneurological studies.

Ontogenetic Changes in Endocranial Anatomy in Gorgosaurus libratus (Theropoda: Tyrannosauridae) Provide Insight Into the Evolution of the Tyrannosauroid Endocranium. [PDF]
J Comp NeurolChanges through growth (ontogenetic) in the braincase of the eutyrannosaurian tyrannosauroid Gorgosaurus libratus are discussed. Most notably, brain cavity endocasts of immature Gorgosaurus are found to more clearly show details of the brain morphology than more mature individuals, a finding that has implications for improving dinosaur paleoneurology ...

Comparative Sulcal Morphology of the Late Miocene Fossil Ape, Rudapithecus hungaricus. [PDF]
Am J Biol AnthropolABSTRACT Objectives Endocasts of fossil hominoids are exceedingly rare. The only fossil ape endocast analyzed in detail is that of Ekembo nyanzae (KNM‐RU 7290), from the early Miocene of Kenya. Two partial crania of Rudapithecus hungaricus, from the late Miocene of Hungary, preserve sufficient details to reconstruct large amounts of endocranial ...

Postnatal interaction of size and shape in the human endocranium and brain structures. [PDF]
J AnatAncestral egg‐laying Sceloporus had dorsoventrally tall female pelvises. Two of three live‐bearing clades evolved larger bodies and flatter, wider pelvises, likely reflecting relaxed allometric limits and selection for crypsis or thermoregulation in terrestrial habitats.

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.

On the “cartilaginous rider” in the endocasts of turtle brain cavities [PDF]
Vertebrate Zoology, 2021 In recent years, paleoneurology became a very popular research field and hundreds of brain-endocasts were described. The interpretation of a dorsal protuberance of the brain-endocast puzzled researchers for a long time, the so-called (cartilaginous ...

Hand to mouth in a Neandertal : right-handedness in regourdou 1 [PDF]
, 2012 We describe and analyze a Neandertal postcranial skeleton and dentition, which together show unambiguous signs of right-handedness. Asymmetries between the left and right upper arm in Regourdou 1 were identified nearly 20 years ago, then confirmed by ...

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
