Aquatic fauna from the Takarkori rock shelter reveals the Holocene central Saharan climate and palaeohydrography

The abundant faunal remains from the Takarkori rock shelter in the Tadrart Acacus region of southwestern Libya are described. The material that covers the period between 10,200 to 4650 years cal BP illustrates the more humid environmental conditions in the Central Sahara during early and middle Holocene times. Particular attention is focussed on the aquatic fauna that shows marked diachronic changes related to increasing aridification.

New investigations in Southern Ethiopia (Yabelo And Gotera). Pleistocene and Holocene archaeological evidence

Vengono qui presentati i risultati della prima campagna di ricerca nell’area di Yabelo e Gotera, in Etiopia meridionale. La ricerca in quest’area è legata al programma (H)ORIGIN, finanziato dal MIUR, che intende investigare il record archeologico relativo all’origine e diffusione di Homo sapiens in Africa. Le aree indagate consistono in due transetti di 100 km² e presentano evidenze promettenti sia per quanto riguarda i siti del Pleistocene, sia per i periodi più recenti.

Investigating the environmental interpretation of oxygen and carbon isotope data from whole and fragmented bivalve shells

Sclerochronological data from whole bivalve shells have been used extensively to derive palaeoenvironmental information. However, little is known about the relevance of shell fragments more commonly preserved in the sediment record. Here, we investigate the oxygen and carbon isotope composition of Dreissena carinata fragments from a core recovered from Lake Dojran (FYRO Macedonia/Greece) to identify their relevance and efficacy as a proxy in palaeoenvironmental studies.
