Reconstructing Smoking Practices at La Granja Site (130 A 1000 Ad, Cachapoal River Valley, Vith Region, Chile) Through Microfossil Evidence
(Univ Tarapacá, 2016)
To broaden the definition of the Smoking Complex proposed for La Granja site (Cachapoal river valley, VIth Region, Central Chile, 130-1000 AD) we have studied the microfossils contained in 62 smoking pipes. Our aim is to ...
