South American Archaeology Series No 20 This book discusses the relationship between mobility and / or archaeological sites functionality and lithic artifacts. The problems encountered when dealing with such issues are presented from different theoretical and / or methodological perspectives and from different spatial and temporal scales. There is a consensus that, from techno-typological analysis, it is possible to infer differential mobility strategies and site functionality. In this regard, the various case studies that are included in the book allow a tour of different ways to approach these issues from lithic artifacts in Argentina, so this book is a reference contribution for both specialists and general public.
