Palaeolithic settlements in Palù di Livenza
Underwater explorations in the Molinetto / Livenzetta allowed us to find flint tools dating back to the last phase of the Italian Upper Paleolithic, between 14,000 and 10,000 years ago.
These remains are related to the presence during the Late Glacial of a lake in the center of the basin.
The wetlands provide a high productivity of plant biomass that attracts a large number of animals, providing a place of great importance for the survival of prehistoric man dedicated to hunting and gathering. The presence of the lake and of abundant natural resources favored the presence of bands of hunters-gatherers practicing the hunting.
The tools used for hunting that were founded in Palù are about 50: pointed tools, spikes and some parting and grooving blades that were used for arming the tip of arrows, harpoons and javelins.
Perhaps the same groups of Palù also lived in Mount Cansiglio , as confirmed by the materials found in the locality of the Bus de la Lum.
The presence of other settlements in the mountain area of Pordenone reveals a pattern of exploitation of the land and its resources, already known in Veneto and Trentino, which included mid-mountain seasonal camps during the summer, complementary to sites of longer duration, placed in valleys or, as in the case of Palù, in the foothills during the winter months.
With the end of the Ice Age, about 10,000 years ago, a more temperate phase began, leading to the gradual drying up of the lake.
The few flint tools, attributable to the Mesolithic, come from the same south-central area of the basin.
The tools include geometric trapezoidal blades and grooves that attest a new attendance of groups of hunters-gatherers during the recent phase of the Mesolithic, known as Castelnovian, and dated between 9,000 and 7,500 years ago.
