pica, together with its body size, coincides with that found in other gastropods such as Ancylus
fluviatilis (Calow, 1975), Buccinum undatum (Kideys, 1998), B.
The hypothetical River Dana was introduced to the scientific discussion to explain the Lake Ancylus
regression via Darss Sill, Fehman Belt (Femern Baelt) and Great Belt (Storebaelt) into Kattegat (von Post 1929, Kolp 1986, Bjorck 1995).
The procedure was repeated for four specimens (two of Ancylus
fluviatilis (A1 & A2), one of Gammarus fossarum (G2), and one of Sericostoma personatum (S2)) with a P7 adapter similar to the ones described above but without the DBR region, to test for the general performance of the adapters with and without DBRs.
concentricus within Basural Beach with that of populations from other Ancylidae genera elsewhere such as Ancylus
fluviatilis Muller, 1774 from Europe, as reported by Geldiay (1956), Durrant (1980), and McMahon (2004) revealed that despite the differences in the latitudes of their habitats, the size frequencies of these species are determined by the ambient water temperature, and their growth rate is the same as one generation per year.

Of those, 45 are connected with the Ancylus
Lake beach formations, 31 with the Litorina Sea, and 9 are younger and of various age.

This has already been observed in the highly selfing pulmonate Ancylus
fluviatilis (Stadler et al.
2007) and some coastal marks from the Ancylus
Lake (9500-8000 yr BP) can be found on the altitudes of up to 45 m (Kessel & Raukas 1967).
The most prominent coastal forms, about 35 m high, are referred to the initial stage of the Ancylus
Lake, when the shoreline remained stable for a long time, favouring the formation of extensive scarps and accumulation of sediments in Tallinn.
Water level in the former Baltic Sea basins (Yoldia Sea or Ancylus
Lake) during the formation of the terraces was a few tens of metres lower than the recent one (Veski et al.
Discussion with specialists in SED would have helped him to understand the limitations of the method and what one can reasonably expect from it, particularly considering that a number of boulders in Estonia were sampled near the Baltic coast and had previously experienced some period of submergence beneath the Baltic Ice Lake, the Ancylus
Lake, and the Litorina Sea.

Therefore, the relatively young weighted mean age of the Palivere zone (10 000 [+ or -] 1300 [sup.10]Be yr BP) between that of the Pandivere zone immediately to the south (13 000 [+ or -] 1100 [sup.10]Be yr BP) and Salpausselka I zone to the north (11 800 [+ or -] 900 [sup.10]Be yr BP) is readily explained by submergence of the boulders by the Baltic Ice Lake, Ancylus
Lake, Litorina Sea, and Limnea Sea, which would have substantially reduced the production rate for that period of time (Rinterknecht et al.
