Are endocasts reliable proxies for brains? A 3D quantitative comparison of the extant human brain and endocast. [PDF]

open access: yesJ 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.

Pachycephalosaur paleoneurology (Archosauria: Ornithischia)

open access: yesJournal of Vertebrate Paleontology, 1989
ABSTRACT Pachycephalosaur endocranial casts display a distinctive suite of traits that include large divergent olfactory bulbs, large olfactory nerves, short thick olfactory tracts, a moderately expanded cerebrum not separated from optic lobes and cerebellum dorsally, steep cranial flexure, and reduced pontine flexure.

Recent Advances in Paleoneurology

open access: yes, 1964
Publisher Summary This chapter illustrates the work being done in paleoneurology recently ascertained in organisms ranging from a crossopterygian fish of some 390 million years ago, Porolepis , to a mammal contemporary Hippopotamus. Paleoneurology cannot agree with the concept, perpetuated in the neontological literature, that increasingly ...

Introduction: Paleoneurology, Resurgent!

open access: yes, 2014
Much has happened in the study of paleoneurology since the turn of the 20th Century involving increasing sophistication of digital methods which permit a variety of statistical and imaging techniques that are replacing the older methods of studying endocasts, which have relied upon plaster/latex rubber copies of fossil materials and mostly qualitative ...

Ontogenetic Changes in Endocranial Anatomy in Gorgosaurus libratus (Theropoda: Tyrannosauridae) Provide Insight Into the Evolution of the Tyrannosauroid Endocranium. [PDF]

open access: yesJ Comp Neurol
Changes 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]

open access: yesAm J Biol Anthropol
ABSTRACT 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 ...

Early synapsids neurosensory diversity revealed by CT and synchrotron scanning. [PDF]

open access: yesAnat Rec (Hoboken)
Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...

Hemispheric asymmetries, paleoneurology, and the evolution of the human genus

open access: yes
Brain asymmetries are a distinctive feature of Homo sapiens and are associated with key evolutionary functions including language and handedness. Nonetheless, differences between humans and apes could be just a matter of degree and size and not the expression of unique traits of our species.

Human paleoneurology: Shaping cortical evolution in fossil hominids

open access: yesJournal of Comparative Neurology, 2019
AbstractEvolutionary neuroanatomy must integrate two different sources of information, namely from fossil and from living species. Fossils supply information concerning the process of evolution, whereas living species supply information on the product of evolution.

Postnatal interaction of size and shape in the human endocranium and brain structures. [PDF]

open access: yesJ Anat
Ancestral 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.
