Paleoindian Lithic Industries of Southern Brazil: A Technological Study of the Laranjito Archaeological Site, Pleistocene-Holocene Transition

Abstract

During the second half of the twentieth century, Brazilian archaeologists organized the Paleoindian sites of southeastern and southern Brazil into an archaeological cultural unit known as the Umbu Tradition. Umbu sites were characterized by the large presence of bifacial points in the lithic industries. However, few studies have been accomplished to determine whether there is technological patterning among the Umbu-related lithic assemblages, especially patterns in flakes and other tools. This article presents new data about the Umbu-related lithic industry from the Laranjito archaeological site. Laranjito is located along the Uruguay River margin, and it has been dated to the Pleistocene-Holocene transition (12,915 ± 116 to 11,904 ± 308 cal yr BP).
