Discovered inside a cave, the ivory statuette depicts a human and a lion. When it was made: 40,000 years ago Carved out of a mammoth tusk, the 12-inch-tall (31 centimeters) artifact would have been difficult to make. In fact, when researchers conducted an experiment years later using ice age tools, including pieces of flint, they determined it would have taken the artisan approximately 400 hours to complete, according to the British Museum. https://www.livescience.com/archaeology/
