  1. Radiocarbon dates of shells and terrestrial macrofossils from a sediment core at Kilen, Limfjorden, Denmark. lf leaf-fragment, lfs leaf-fragments, bs bud-scale, bss bud-scales, t twig, tf twig-fragment. Scirpus seed: Scirpus maritimus/ lacustris. Numbers in squared brackets denote minimum salinity tolerances according to Sorgenfrei (1958). δ13C marked by an asterisk were measured by the accelerator and can only be used for normalisation of the 14C dating, not for drawing palaeoenvironmental conclusions. Some samples were too small to allow for δ13C measurements; in these cases, δ13C = -27‰ was assumed to normalise the 14C dating.
