    Pliopithecoids are an extinct group of catarrhine primates from the Miocene of Eurasia. More than 50 years ago, they were linked to hylobatids due to some morphological similarities, but most subsequent studies have supported ...
  • Comparative anatomy of the carotid canal in the Miocene small-bodied catarrhine Pliobates cataloniae 
    Bouchet, Florian; Urciuoli, Alessandro; Beaudet, Amelie; Pina, Marta; Moya-Sola, Salvador; Alba, David M. (Elsevier, 2021-12)
    The small-bodied Miocene catarrhine Pliobates cataloniae (11.6 Ma, Spain) displays a mosaic of catarrhine symplesiomorphies and hominoid synapomorphies that hinders deciphering its phylogenetic relationships. Based on ...
  • The emergence of language in the hominin lineage : perspectives from fossil endocasts 
    Beaudet, Amelie (Frontiers Research Foundation, 2017-08-23)
    Since brain does not fossilize, brain endocast (i.e., replica of the inner surface of the braincase, Figure ​Figure1)1) constitutes the only direct evidence for reconstructing hominin brain evolution (Holloway, 1978; ...
  • The endocranial shape of Australopithecus africanus: surface analysis of the endocasts of Sts 5 and Sts 60 
    Beaudet, Amelie; Dumoncel, Jean; De Beer, Frikkie; Durrleman, Stanley; Gilissen, Emmanuel; Oettle, Anna Catherina; Subsol, Gerard; Thackeray, John Francis; Braga, Jose (Wiley, 2018-02)
    Assessment of global endocranial morphology and regional neuroanatomical changes in early hominins is critical for the reconstruction of evolutionary trajectories of cerebral regions in the human lineage. Early evidence ...
  • Endostructural assessment of a hominin maxillary molar (StW 669) from Milner Hall, Sterkfontein, South Africa 
    Mataboge, Bontle; Beaudet, Amelie; Heaton, Jason L.; Pickering, Travis R.; Stratford, Dominic (Academy of Science of South Africa, 2019-09)
    The site of the Sterkfontein Caves, South Africa, is one of the richest early hominin fossil-bearing sites in Africa. Recent excavations in the Milner Hall locality have contributed to the discovery of new hominin specimens, ...
  • The evolution of the vestibular apparatus in apes and humans 
    Urciuoli, Alessandro; Zanolli, Clement; Beaudet, Amelie; Dumoncel, Jean; Santos, Frederic; Moya-Sola, Salvador; Alba, David M. (eLife Sciences Publications, 2020-03-03)
    Phylogenetic relationships among extinct hominoids (apes and humans) are controversial due to pervasive homoplasy and the incompleteness of the fossil record. The bony labyrinth might contribute to this debate, as it ...
  • A frontal lobe surface analysis in three archaic African human fossils : OH 9, Buia, and Bodo 
    Beaudet, Amelie; Bruner, Emiliano (Elsevier, 2017-08)
    The evolution of the frontal lobes represents a major issue in paleoneurology. In this survey, we used a surface analysis to describe the frontal morphology of three relevant East African specimens from early and middle ...
  • Hominin cranial fragments from Milner Hall, Sterkfontein, South Africa 
    Beaudet, Amelie; Heaton, Jason L.; L'Abbe, Ericka Noelle; Pickering, Travis R.; Stratford, Dominic (South African Society for Animal Science, 2018-11-27)
    The Sterkfontein Caves site is one of the richest early hominin localities in Africa. In addition to significant fossil assemblages from Members 2 and 4 of the Sterkfontein Formation, recent excavations have revealed ...
  • The inner craniodental anatomy of the Papio specimen U.W. 88-886 from the Early Pleistocene site of Malapa, Gauteng, South Africa 
    Bouchet, Florian; Ribéron, Alexandre; Heaton, Jason L.; Hoffman, Jakobus; Bam, Lunga; Jakata, Kudakwashe; Tawane, Mirriam; Tenailleau, Christophe; Zipfel, Bernhard; Beaudet, Amelie (Evolutionary Studies Institute, University of Witwatersrand, 2019)
    Cercopithecoids represent an essential component of the Plio-Pleistocene faunal assemblage. However, despite the abundance of the cercopithecoid fossil remains in African Plio-Pleistocene deposits, the chronological and ...
  • The inner ear of the Paranthropus specimen DNH 22 from Drimolen, South Africa 
    Beaudet, Amelie (Wiley, 2019-11)
    OBJECTIVES : Morphological variation within the southern African hypodigm of Paranthropus has been the focus of major interest since the earliest discoveries in the “Cradle of Humankind.” Given the relevance of the bony ...
