From Smart Apes to Human Brain Boxes. A Uniquely Derived Brain Shape in Late Hominins Clade
Frontiers in Earth Science, 2020 Modern humans have larger and more globular brains when compared to other primates. Such anatomical features are further reflected in the possession of a moderately asymmetrical brain with the two hemispheres apparently rotated counterclockwise and slid ...

Morphometric analysis of lungfish endocasts elucidates early dipnoan palaeoneurological evolution
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 ...

Braincase anatomy of the Paleocene crocodyliform Rhabdognathus revealed through high resolution computed tomography [PDF]
PeerJ, 2021 Dyrosaurids were highly specialized, largely marine, relatives of living crocodylians, and one of the few archosaur lineages to survive the K-Pg extinction.

Journal of Anatomy, 2020 AbstractEndocasts (i.e., replicas of the inner surface of the bony braincase) constitute a critical proxy for qualifying and quantifying variations in brain shape and organization in extinct taxa. In the absence of brain tissues preserved in the fossil record, endocasts provide the only direct evidence of brain evolution. However, debates on whether or

, 2011 International audienceThe Taung type specimen for Australopithecus africanus includes a natural endocast that reproduces external morphology of a large portion of the right cerebral hemisphere, and a separate fragment of the fossilized face that ...

Diversity, 2020 The shape of the brain influences skull morphology in birds, and both traits are driven by phylogenetic and functional constraints. Studies on avian cranial and neuroanatomical evolution are strengthened by data on extinct birds, but complete, 3D ...

A fresh look at Cladarosymblema narrienense, a tetrapodomorph fish (Sarcopterygii: Megalichthyidae) from the Carboniferous of Australia, illuminated via X-ray tomography [PDF]
PeerJ, 2021 Background The megalichthyids are one of several clades of extinct tetrapodomorph fish that lived throughout the Devonian–Permian periods. They are advanced “osteolepidid-grade” fishes that lived in freshwater swamp and lake environments, with some taxa ...

Paleoneuroanatomy of the aetosaur Neoaetosauroides engaeus (Archosauria: Pseudosuchia) and its paleobiological implications among archosauriforms [PDF]
PeerJ, 2018 The paleoneuroanatomy of pseudosuchian archosaurs is poorly known, based on direct examination of the internal morphology of braincases and a few artificial endocasts.

Automatic extraction of endocranial surfaces from CT images of crania. [PDF]
PLoS ONE, 2017 The authors present a method for extracting polygon data of endocranial surfaces from CT images of human crania. Based on the fact that the endocast is the largest empty space in the crania, we automate a procedure for endocast extraction by integrating ...

The circle of Gánovce: natural history of an endocast.
Journal of anthropological sciences = Rivista di antropologia : JASS, 2019 The natural endocranial cast of Gánovce was found in Slovakia in 1926, and then stored in the National Museum (Národní Muzeum) of Prague. The endocast was extensively studied by Emanuel Vlček (1925-2006), mostly during the 50s and 60s of the past century (e.g., Vlček, 1949, 1953, 1955, 1969), with a large set of analytical tools including ...
