According to their reconstructed paleogeographic map
, the domain corresponding to present-day Estonia likely started to receive terrigenous clastics not only from the core of Baltica in the north/ west, as was the case during the Ediacaran, but also from uplifted areas in the east/southeast since the Early Cambrian appearance of this embayment.
One locality plotted in the middle of the seaway on each paleogeographic map from the Cretaceous which overlapped the localities current age assignment.
The creation of such maps requires three things; an extensive database of fossil molluscan taxa, paleogeographic maps, and geologic maps.
A completely revised suite of over 250 paleogeographic maps
is now available across all 32 regions of the Tellus world.
