The oldest boomerang in the world is older than previously thought, and this puts new revelations into the human creativity that lived at that time.
The tool was discovered in a cave in Poland in 1985 and is now believed to be 40,000 years old.
Archaeologists say it is made from the tusks of mammoths with amazing skills.
The researchers trained out of the shape that would fly when thrown, but would not return to the thrower.
It may be used for hunting, although it may have cultural or artistic value, perhaps used in some kind of ritual.

Mammoth ivory boomerang was excavated in the Oblazowa cave in southern Poland.
It was initially thought to be 30,000 years old. However, new, more reliable radiocarbon ages of human and animal skeletons found at the site put the ages between 39,000 and 42,000 years.
“This is the oldest boomerang in the world and the only person in the world made of this shape, and this shape can be found in Poland,” said Dr. Sahra Talamo of the University of Bologna in Italy.
She said it had an “extraordinary insight” into human behavior, especially how Homo sapiens’ life 42,000 years ago could shape “such a perfect object” and could be used to hunt animals.
The boomerang is very preserved, with the score mark indicating that it has been polished and engraved for right hand use.

Boomerang is often associated with the Aboriginal culture of Australia.
However, rare findings have been found in historical records outside Australia, suggesting they are used between different continents.
From Australia to the oldest Boomerang about 10,500 years ago, made of wood. But the oldest image of Boomerangs in Australia is 20,000 years of rock art paintings, according to the National Museum of Australia.
A wooden boomerang dating back to 7,000 years was found in Jutland, the peninsula between Denmark and Germany, while fragments of a 2,000-year-old Oak Boomerang were found in the Netherlands.
Research by a team of scientists from Poland, Italy, Germany, France, Switzerland and the United Kingdom is published in the Journal PLOS one.
