Paglicci 24A1 and Mira II/2: Episode at the transition between the Early and Middle UP.

The aim of this paper is to present the evidence for, and to discuss the aspects of the striking similarities that have been identified between backed bladelets recovered in two geographically distant assemblages, one found in Southern Italy (Paglicci, layer 24 horizon A1) and the other in Eastern Europe (Mira, layer II horizon 2). Both assemblages are dated to around 29–28,000 BP and are taxonomically defined as Early Upper Palaeolithic. Detailed comparison of technical and morphological data is impossible because the Eastern European site does not contain an assemblage that lends itself to statistical analysis. The backed bladelets of type PA24A1, found in Paglicci, layer 24 horizon A1-0, and Mira, layer II horizon 2, have no direct analogies in chronologically close Aurignacian and Gravettian sites, in either Southern or Eastern Europe. Taking into account the similar chronological position of the sites, separated by a distance of ca. 2,500 km, it is concluded that the significant similarity of the backed bladelets is most likely explained not by the convergence of development or by trade, but by the direct migration of a group of modern humans who manufactured such specific microliths. The Paglicci (24A 1) and Mira (II/2) industries generally belong to the Early Upper Palaeolithic, being placed chronologically at the transition between the EUP and MUP, being located morphologically and technologically between the Aurignacian and Gravettian. Despite the scarcity of data, the distinctiveness of the backed implements indicates that the sites belong to the same episode of sociocultural development. The issue of the cultural affiliation of the industry with PA24A1 type bladelets remains unanswered, and the search for analogies, either in Eastern or Southern Europe, needs to be continued.
