Archaeologists have actually uncovered a 4,000-year-old copper dagger and pieces of human skulls deep in a collapse Italy. The cavern was plainly utilized for burials, however it likewise holds the remains of an ancient hearth.

“The moment we discovered the dagger was unforgettable,” Federico Bernardinian archaeologist at Ca’Foscari University in Venice, informed Live Science. “We could hardly believe it — finding metal artifacts, especially a dagger, was completely unexpected in this context.”

Burials in caverns or rock shelters prevailed in this area at this time, in between 4,500 and 4,000 years earlier, throughout the late Copper Age (2750 to 2200 B.C.)and early Bronze Age(2200 to 950 B.C.). The dagger discovery was unforeseen due to the fact that such unusual finds from these durations are generally at locations of praise, stated Bernardini, who is leading the dig for the university in collaboration with other Italian and Slovenian organizations and authorities.

“As we carefully removed the final layers of soil, a flash of copper caught our attention,” Bernardini stated in an e-mail, including that they right away acknowledged the significance of the finding.

The dagger is among a number of artifacts discovered in Tina Jama Cave, in the “Karst Plateau” of exposed and greatly weathered limestone along Italy’s northeast border with Slovenia. In addition to other finds from the cavern, the dagger is assisting to determine the age and technological abilities of the various groups of individuals who inhabited the cavern at numerous times in between 9,000 and 4,000 years back.

“The investigations are still ongoing, but they are allowing us to gather valuable data to reconstruct the area’s prehistory,” Bernardini stated.

Ancient cavern

According to an equated declaration from the university, the excavations have actually exposed layers from the lasts of the Copper Age and the start of the Bronze Age, before the trick of including tin to copper to make bronze was understood.

In specific, the finds from the 2nd half of the 3rd millennium B.C. are “crucial for understanding the technological, cultural, and social transformations of Europe at that time,” Elena Leghissaan archaeologist with the Slovenian Academy of Sciences and Arts who is leading the Slovenian group, stated in the declaration.

The archaeologists are “employing a rigorous methodological approach” while excavating the cavern, Bernardini stated, consisting of making use of “structure-from-motion photogrammetry” to develop virtual 3D maps from two-dimensional images.

In addition, “the soil is carefully sieved with a 1mm mesh to collect as much information as possible,” he stated.

Strange stones

Among the strangest functions of Tina Jama Cave is a structure that closed the entryway with stone pieces and blocks. It is believed to date to in between 2000 and 1500 B.C., or approximately 500 years after the dagger was positioned there.

The structure’s function is unidentified, and it might have been built to shelter the cavern’s interior from the strong and cold “bora” wind that blows in this area from the northeast every winter season. The archaeologists likewise believe it might have been related to burials in the cavern, due to the fact that pieces of human skulls have actually been discovered close by.

“The skull fragments indicate that the cave was used as a burial place at certain times, though we need to wait for radiocarbon dating to better understand their chronology and possible connection with the stone structure,” Bernardini stated.

The excavations have actually likewise exposed a “hearth” or fireplace that appears to be older than the stone structure at the cavern’s entryway. It recommends that, “prior to the construction of the stone structure, groups of people used the cave entrance,” Bernardini stated. “Based on part three findings, these groups seem to be associated with the Cetina culture from the Dalmatian region in modern-day Croatia,” an early Bronze Age individuals, he informed Live Science.
