Other archaeological evidence from the site suggests the ancient inhabitants were amongst the world's first farmers, consuming emmer (a type of wheat), barley, chickpeas and lentils, and herding or hunting goats, gazelles, pigs and deer, the authors write in the March issue of the journal Antiquity.
Mysterious wand After the skeletons and wand were buried, someone seems to have dug up and removed the skulls, placing them in the inhabited portion of the settlement.
The bone wand was likely carved from the rib of an auroch, the wild ancestor of cows, and was about 4.7 inches (12 centimeters) long. Two natural-looking faces, with eyes closed, were carved into the bone, though the wand was intentionally broken at both ends, with more faces likely originally adorning the staff.
The relic's purpose and symbolism remain a mystery.
"It's clearly linked to funerary rituals, but what kind of rituals, it's impossible to tell," Braemer told Live Science.
The find marks a transition in culture toward more interest in the human form. Older artifacts typically showed stylized or schematic representations of humans, but realistic depictions of animals. Art unearthed in what is now Jordan and Anatolia from the same time period also employs delicate, natural representations of the human form, suggesting this trend emerged simultaneously in regions throughout the Middle East, Braemer said.
