The scientists unearthed large earthenware jars in the excavation field and the skeletons were preserved inside, Excavation Head Francesca Balossi Restelli said, adding that they belong to 3,600 B.C.

The skeletons are from the late chalcolithic period, Restelli noted, adding that further testing will reveal the exact date they are from, as well as whether the children suffered from any diseases. 

Excavation work in the mound has progressed as far as the floors of the houses in the ancient settlement, Restelli noted, adding that they've found an abundance of ceramics in the homes.

"A variety of ceramics in different sizes. We found pots, cups and cupboards made out of seeds and mud," Restelli said.
