Endostructural characterization of the H. heidelbergensis dental remains from the early Middle Pleistocene site of Tighenif, Algeria

The origin and evolution ofHomo sapiens

“…In considering dental morphology, we are severely limited by the lack of good data for this period from sub-Saharan Africa, while further north the Tighennif fossils from Algeria have been considered more primitive than the antecessor material [113]. However, endostructurally, the Tighennif dentitions were considered close to the status of a Neanderthal-modern LCA by Zanolli & Mazurier [114]. There are perhaps also clues in the form of the Qesem teeth from Israel, which are of comparable age to or slightly younger than the Sima de los Huesos fossils (approx.…”

Root Canal Morphology of Chalcolithic and Early Bronze Age Human Populations of El Mirador Cave (Sierra de Atapuerca, Spain)

“…In the field of paleoanthropology, the research related to internal root morphology has been focused on taurodontism (Harvati et al, 2003;Rosas et al, 2006;Kupczik and Hublin, 2010), analyses of dentine thickness in the dental roots of Neanderthals (Bondioli et al, 2010) and root canal morphology in Early and Middle Pleistocene populations (Prado-Sim on et al, 2012;Zanolli and Mazurier, 2013). To our knowledge, little work has been published determining Chalcolithic and Early Bronze Age human root canal anatomy with CBCT.…”

Enamel thickness and enamel growth in Oreopithecus: Combining microtomographic and histological evidence

“…Indeed, while the main cusps are externally well differentiated, the short precingulid accessory cusps (i.e., paraconid, centroconid, tuberculum sextum) and the complex crest network (i.e., the paracristid between paraconid and protoconid, the protocristid between protoconid and metaconid, the hypolophid between hypoconid and entoconid, the hypometacristid between metaconid and centroconid, the hypoprotocristid between protoconid and centroconid, and the entolophid between entoconid and hypoconulid) (Butler and Mills, 1959) are more markedly expressed at the EDJ. In fact, compared to the OES signal, sharper topographic information of taxonomic and phylogenetic value is commonly observed in extant and fossil hominids at the EDJ level (Corruccini, 1987;Macchiarelli et al, 2006Macchiarelli et al, , 2009Olejniczak et al, 2004Olejniczak et al, , 2007Skinner et al, 2008a,b;Smith et al, 2006Smith et al, , 2009Zanolli and Mazurier, 2013).…”

“…i This study. and dentine horns enclosing a sub-concave occlusal basin commonly seen in fossil and extant hominoid molars, such as Ouranopithecus (Macchiarelli et al, 2009), Paranthropus and Australopithecus , Homo Skinner et al, 2008b;Zanolli, 2014;Zanolli and Mazurier, 2013), and in the living great apes (Skinner et al, 2008b(Skinner et al, , 2010. Assuming that Oreopithecus is closely related to the dryopithecines (Harrison and Rook, 1997;Moyà-Solà and Köhler, 1997), which almost invariably exhibit a low to only moderately elevated external crown topography (Alba et al, 2013;Begun, 2002), its tall occlusal reliefs could represent an autapomorphic feature developed under conditions of insular isolation.…”
