The early modern human remains from the Peştera Muierii, Romania have been directly dated to Ϸ30,000 radiocarbon years before present (Ϸ30 ka 14 C BP) (Ϸ35 ka cal BP) (''calendrical'' age; based on CalPal 2005) and augment a small sample of securely dated, European, pre-28 ka 14 C BP (Ϸ32.5 ka cal BP) modern human remains. The Muierii fossils exhibit a suite of derived modern human features, including reduced maxillae with pronounced canine fossae, a narrow nasal aperture, small superciliary arches, an arched parietal curve, zygomatic arch above the auditory porous, laterally bulbous mastoid processes, narrow mandibular corpus, reduced anterior dentition, ventral-to-bisulcate scapular axillary border, and planoconcave tibial and fibular diaphyseal surfaces. However, these traits co-occur with contextually archaic and͞or Neandertal features, including a moderately low frontal arc, a large occipital bun, a high coronoid process and asymmetrical mandibular notch, a more medial mandibular notch crest to condylar position, and a narrow scapular glenoid fossa. As with other European early modern humans, the mosaic of modern human and archaic͞Neandertal features, relative to their potential Middle Paleolithic ancestral populations, indicates considerable Neandertal͞modern human admixture. Moreover, the narrow scapular glenoid fossa suggests habitual movements at variance with the associated projectile technology. The reproductive and scapulohumeral functional inferences emphasize the subtle natures of behavioral contrasts between Neandertals and these early modern Europeans.cranium ͉ Europe ͉ Late Pleistocene ͉ Neandertals ͉ Upper Paleolithic

During the process of direct radiocarbon dating of four Early Upper Paleolithic modern humans from the Romanian sites of Peştera cu Oase, Peştera Muierii and Peştera Cioclovina Uscată, carbon and nitrogen stable isotope ratios (δ13C and δ15N) were measured from their bone collagen. These individuals have δ13C values similar to other Late Pleistocene humans. Their δ15N values are well within the carnivore trophic level range, among the higher of the Middle Upper Paleolithic values, and significantly greater than those of preceding Middle Paleolithic and Initial Upper Paleolithic Neanderthals. These data suggest a shift towards a broader faunal dietary spectrum among these early modern humans, despite western and eastern European archeological evidence and human functional morphology indicating little change in faunal exploitation from the Middle Paleolithic to the Early Upper Paleolithic.

Owing to a thick blanket of loess and other later geological disruptions, the earliest hominins to reach Europe are hard to find. To a handful of possible sites, our authors add a new assemblage of lithics with a clear local context and corroborated OSL ages. Ancient humans were present in what is now Romania between 300 000 and 400 000 years ago.
