Abstract

A morphometrical study of hundreds of spikelets recovered from archaeological deposits of Takarkori (SW Libya) provides data on the presence and size variations of wild cereals gathered by hunter-gatherers in the central Sahara during the Early and Middle Holocene (c. 10,200–c. 4600 cal yr BP). Spikelets of Panicum laetum, Echinochloa colona and Sorghum bicolor subsp. verticilliflorum, found in 18 seed/fruit concentrations, are measured using image analysis techniques. These data demonstrate that the archaeobotanical specimens have a similar typology, maturity stage and are of a uniform size, suggesting that they were selected by the human groups living in the area. Indeed, the spikelets of two samples recovered from sediments excavated elsewhere on the site compared to those from the seed concentrations, show a smaller size and greater variation in maturation status. Results are compared to metrical data obtained from modern species.

We thank the Italian-Libyan Archaeological Mission in the Acacus and Messak, directed by Savino di Lernia, which allowed the sampling and the analysis of the plant remains from Takarkori. The research was part of the PhD project of R.F. at the School Agri-food Science, Technologies and Bio-technologies (University of Modena and Reggio Emilia). Funds were provided by the project “SELCE—SELvatici CEreali: il futuro nella risposta delle piante ai cambiamenti climatici”, sect. Scientific and Technological Research (Sime n.2015.0033), funded by the FCRMO-Fondazione Cassa di Risparmio di Modena, directed by A.M.M.
