The Lagar Velho site is a rock-shelter in the Lapedo valley, a limestone canyon ca. 140 km north of Lisbon in central Portugal.
In 1998, the discovery of an early Upper Paleolithic human burial in this site has provided evidence of early modern humans from southern Iberia. The remains, the largely complete skeleton of an approximately 4-year-old child buried with pierced shell and red ochre, is dated to ca. 24,500 years B.P. The cranium, mandible, dentition, and postcrania present a mosaic of European early modern human and Neanderthal features.[citation needed] The temporal bone has an intermediate-sized juxtamastoid eminence. The mandibular mentum osseum and the dental size and proportions, supported by mandibular ramal features, radial tuberosity orientation, and diaphyseal curvature, as well as the pubic proportions align the skeleton with early modern humans. Body proportions, reflected in femorotibial lengths and diaphyseal robusticity plus tibial condylar displacement, as well as mandibular symphyseal retreat and thoracohumeral muscle insertions, align the skeleton with the Neandertals.[citation needed] This morphological mosaic indicates admixture between regional Neanderthals and early modern humans dispersing into southern Iberia.[citation needed] It establishes the complexities of the Late Pleistocene emergence of modern humans and refutes strict replacement models of modern human origins.
