Fig. 2. Recalibrated bulk radiocarbon datesfrom Tjørnuvík (Profiles A, B and C) (Jóhansen, 1971; 1985) and
AMS radiocarbon date of terrestrial plant macrofossils from the present study (Profile D). The central tine
indicates the settlement horizon as identified by pollen analysis in each profile. Numbers on the left hand side of
each profile indicate depth below surface in each bulk sediment section. Profile D indicates sampte sizefrom
which plant macrofossils were extracted although the sediment itselfwas not dated.

abundant calyces of Gramineae and seeds
of Caltha palustris. These species do not
occur below the settlement horizon where
macroremains of Menyanthes trifoliata,
Ranunculus flammula, Sedum villosum,
Hypericum pulchrum and Equisetum palus-
tre predominate.
Dating
Macrofossil material picked for dating the
settlement horizon were seeds of Montia
fontana, Sedum villosum, Stellaria media,
Silene dioica and sporangial cones of Equi-
setum palustre. This revealed that the first
crop cultivation was at 1270 ± 60 years BP,
which when calibrated covers the time pe-
riod from AD 675-861 (1 CT variation;
CALIB vers. 3.0.3; Stuiver and Pearson,
1993), confirming the earlier results at this
site; the first permanent settlement, as rep-
resented by crop cultivation was earlier
than that suggested by the written, sec-
ondary sources (Figure 2, Table 2).
