Researchers from the University of Gothenburg, Sweden, have spent many years studying the remains of a Stone Age community in Karleby outside the town of Falköping, Sweden. The researchers have for example tried to identify parts of the inhabitants’ diet. Right now they are looking for evidence that fertilisers were used already during the Scandinavian Stone Age, and the results of their first analyses may be exactly what they are looking for.
Using remains of grains and other plants and some highly advanced analysis techniques, the two researchers and archaeologists Tony Axelsson and Karl-Göran Sjögren have been able to identify parts of the diet of their Stone Age ancestors.
‘Our first task was to find so-called macrofossils, such as old weed seeds or pieces of grain. By analysing macrofossils, we can learn a lot about Stone Age farming and how important farming was in relation to livestock ranching,’ says Axelsson.
