The Danish fish fauna during the warm Atlantic period (ca. 7000-3900 bc): Forerunner of future changes?
Vast amounts of fish bone lie preserved in Denmark's soil as remains of prehistoric fishing. Fishing was particularly important during the Atlantic period (ca. 7000-3900 bc, i.e. part of the Mesolithic Stone Age). At this time, sea temperature and salinity were higher in waters around Denmark t...
