The archaeologist told the Polis Press Agency (PAP): “What is interesting, is different funeral rituals were practised.
“Some of the dead were burned and their remains were placed in ceramic urns or directly in pits, some were buried without cremation.
“It was the discovery of the skeletal pits that was surprising to us.”
In a bid to keep the discovered urns intact, the archaeologists employed the aid of a local veterinarian in the town of Dębno.
The veterinarian X-rayed the urns to reveal the secrets lurking inside, without cracking their seals.
