This story is at www.eurekalert.org/pub_releases/2015-03/fm-era030415.php … and concerns ongoing excavations at Diros Bay in Greece. The remains of an ancient settlement and graveyard (with megalithic tombs) has been unearthed, dating back to the Neolithic. Significantly, the site was in use between 6300 and 3000BC. During the 4th millennium BC Greece had wide trading networks – by sea and by land. Copper tools are also evident – prior to the Bronze Age (after 3000BC).
However, the discovery of a Mycenaean period burial structure filled with the disarticulated bones of dozens of people, a Neolithic trait, plus Late Bronze painted pottery, stone beads, ivory, and a bronze dagger of Mycenaean style, seems to suggest the megalithic buildings at Diros Bay were re-used in the LB period – some 2000 years after they had been abandoned.
