Satellite imagery has revealed a connection of more than 100 Bronze Age structures hidden in the Serbian plains .

archeologist first noticed the remnants of the more than 3,000 - twelvemonth - old enclosure in 2015 while reviewingGoogle Earthphotos of a 93 - nautical mile reach ( 150 kilometer ) of wilderness along Serbia ’s Tisza River , according to a study published Nov. 10 in the journalPLOS One .

" We could see traces of over 100 tardy Bronze Age settlements , " study lead authorBarry Molloy , an associate prof of archaeology at University College Dublin , told Live Science in an electronic mail . " What is entrancing about the [ sites ] is that we not only key their presence in these images , but also measured their sizing and , for many , how people form the layout inside their settlements . "

He added , " It is quite unequaled in European Bronze Age archeology to get this floor of detail for so many settlements in such a specific area . "

Previously , this area , known as the Pannonian Plain , was cerebrate to be a hinterland not used for Bronze Age village . But now , researchers think that this is just one example of the many settlements found across Europe that are part of an extensive patronage web from the sentence .

In addition to analyzing orbiter images , for the new survey , investigator gossip the situation via modest woodworking plane and in somebody and found the footprints of dozens of construction " shroud in plain stack , " harmonize toScience cartridge clip .

Most of the enclosures were build close together , similar to neighborhoods today , propose that the denizen " chose to exist together very closely " in what Molloy described as a " complex and well - organized high society . "

" The wan filth patch do not follow any specific alignments , but they are equally go around out , lying a few tens of meters aside from each other , " Molloy said . " While we need to turn up to confirm details , our suspicion is that these were places where unfold families lived . "

Due to farmers plowing the land for many years , the outline of many of the enclosing were much invisible from the solid ground . However , archaeologists did encounter what was left of several wall and ditches , which may have been used as ramparts to help protect the settlement , according to the written report .

" Unfortunately , these only stay visible in aerial figure of speech because they have been fill in and plow down over C of agriculture , including intensive plowing during the 20th hundred , " Molloy said . " A wooden palisade or wall may have ladder around the top of the ramparts , as we see at other sites in the area . "

research worker also unearth " large amount " of artifacts including craunch Stone used for processing grain , clayware shards and pieces of bronze , include a pin used for fastening clothing . Radiocarbon geological dating of animal bones strewn about the site confirm its ancient line of work , Molloy said .
