The endocast morphology of LES1, Homo naledi
American Journal of Biological AnthropologyInternational audienceThe evolutionary diversity across the genus Homo encompasses variation in brain size and overall brain shape. Homo naledi, from the Rising Star cave system of South Africa, is near the extreme of small brain size within Homo but is ...

Endocasts of ornithopod dinosaurs: Comparative anatomy
2023Ornithopod dinosaurs were a successful group before they became extinct at the end of the Cretaceous. They were present on every continent, though they were rare in the Southern Hemisphere. We present the results of our work on the brain of these dinosaurs as an attempt to determine which evolutionary trends affected it.

Brief communication: New reconstruction of the Taung endocast
American Journal of Physical Anthropology, 2007AbstractEarlier reconstructions of the Taung endocast, from the juvenile type specimen for Australopithecus africanus, were achieved without benefit of the advanced computer technology that is available today and before morphological differences were identified that distinguish endocasts of Paranthropus from those of A. africanus.

Parietal lobe variation in cercopithecid endocasts
American Journal of Primatology, 2019AbstractIn extant primates, the posterior parietal cortex is involved in visuospatial integration, attention, and eye‐hand coordination, which are crucial functions for foraging and feeding behaviors. Paleoneurology studies brain evolution through the analysis of endocasts, that is molds of the inner surface of the braincase.

AbstractThe endocranial cast of Tetonius homunculus, a 55 million year old tarsioid primate, is primitive in having relatively large olfactory bulbs and small frontal lobes, but remarkably advanced for an Early Eocene mammal in its voluminous occipital and temporal lobes.

On a new australopithecine partial endocast
American Journal of Physical Anthropology, 1979AbstractA newly discovered right parietal/temporal/frontal fragment from an australopithecine natural endocast is described and compared to other australopithecine endocasts. This specimen shows that the central sulcus was arched, rather than straight as previously believed, and reveals frontal lobe convolutions not preserved in other australopithecine

Technical note: The midline and endocranial volume of the Taung endocast
American Journal of Physical Anthropology, 2011AbstractThe Taung endocast is one of the best‐preserved and most important known in paleoanthropology. Although the endocast is undistorted and preserves distinctive landmarks, Taung has proved a difficult endocast, because it is only about 60% complete.

The Taung endocast: A reply to Holloway
American Journal of Physical Anthropology, 1983AbstractIndices of rostrality (ir, ir′) are developed to assess the extent to which the medial end of the lunate sulcus (L) is rostrally positioned in photographs and figures of lateral views of primate brains and endocasts, and indices are determined for chimpanzees, SK 1585 and the Taung endocast.

A landmarking protocol for geometric morphometric analysis of squamate endocasts
The Anatomical Record, 2023AbstractLandmark‐based geometric morphometrics is widely used to study the morphology of the endocast, or internal mold of the braincase, and the diversity associated with this structure across vertebrates. Landmarks, as the basic unit of such methods, are intended to be points of correspondence, selected depending on the question at hand, whose proper

A reanalysis of the South African australopithecine natural endocasts
American Journal of Physical Anthropology, 1980AbstractSulcal patterns of six previously available South African australopithecine natural endocasts are reexamined and compared to sulcal patterns of 17 human, 12 gorilla and six chimpanzee brains. In addition, a seventh natural endocast, from STS 58, is described for the first time and compared to an artificial endocast from the same specimen. Using
