In addition to their undeniable aesthetic value, ornaments are the element that may differentiate the various social groups or individuals belonging to certain groups. More specifically, body decoration is closely related to social identity. The ornament, as a form of communication, has a certain advantage over other means of communication because, once displayed, perhaps even more than language itself, the individual wearing it need not make any effort to deliver his/her message, social sta-tus, their belonging to a group etc. The first adornments used during the Paleolithic are beads, while perforated shells are among the earliest examples of this sort. In a few cases, the perforated shells come from species rarely used in the Paleolithic, brought from long distances, in terms of the settlements in which they were found so, apart from individualizing and characterizing a certain group, they may represent important documents regarding migrations over wide areas and even regarding the origin of a culture. This is shown by new discoveries made in an early Gravettian layer at the Poiana Cireului site (Piatra Neam, north-eastern Romania), dated between 30 ka and 31 ka BP (Niu et al., 2019). The ornaments discovered here include a unique association of perforat-ed shells represented by three species of mollusks: Lithoglyphus naticoide, Litho-glyphus apertus and Homalopoma sanguineum (an exclusively Mediterranean spe-cies). This occupation differs from Central and Eastern European Gravettian tradi-tions through the symbolic behavior of the communities, defined by the use of perfo-rated shells of freshwater and marine (Mediterranean origin) mollusk belonging to species very rarely used in the Palaeolithic. Poiana Cireului is one of the very few Gravettian sites where perforated Homalopoma sanguineum shells were found and is the only Gravettian settlement where Lithoglyphus naticoides shells were used. We present the ornaments discovered and the results of analysis performed to identify the perforation methods and the use-wear traces. The presence of a Mediterranean species at the Poiana Cireului settlement located more than 900 km from the nearest source suggests the connection of communities here with the Mediterranean area. In the light of these new findings, the origin and diffusion of the Gravettian from the Mediterranean to the east of the Carpathians are a hypothesis that should be considered.
