Fig. 6. RSL reconstructions in central Spain (#1), northern Spain (#2) and central France (#3). Index points (boxes) are plotted as calibrated age against change in sea level relative to
present. Limiting points are plotted as terrestrial or marine horizontal lines. Dimensions of boxes and lines for each point based on 2s elevation and age errors. The relative sea-level
data is compared to a prediction (red line with minimum and maximum errors) from the SELEN model (see Section 4). Al, Alicante; Va, Valencia. Ed, Ebro Delta; Cu, Cubelles; Ll, Llobregat

The RSL history of the northeastern Ligurian Sea is based on 21 index
The RSL database of the western Ligurian Sea consists of 19 index points and 9 limiting points from cores on the Versilia plain and the
points and 18 limiting dates (Fig. 7, #4). Archeological excavations in Arno river coastal plain (Fig. 7, #5). Additional data-points derive from
the ancient harbours near Frejus and Genova provided index and archaeological investigations near Pisa and La Spezia. RSL was at
limiting points. Additional data derived from cores performed on −45.1 ± 1.1 m at ~12.5 ka BP. Then, basal index points indicate that

Index points also derived from L. byssoides samples collected near at ~6.6 ka BP. RSL rise slowed down in the remaining part of the Holo-
