A large conch shell overlooked in a museum for decades is now thought to be the oldest known seashell instrument – and it still works.

The shell was found during the 1931 excavation of a cave with prehistoric wall paintings in the French Pyrenees and assumed to be a ceremonial drinking cup. Archaeologists from the University of Toulouse recently took a fresh look and determined it had been modified thousands of years ago to serve as a wind instrument. They invited a French horn player to play it.
Archaeologist Carole Fritz feared that playing the 12-inch (31-centimeter) shell might damage it, but it didn't. The horn produced clear C, C sharp and D notes.
The researchers estimate it to be around 18,000 years old. Their findings were published Wednesday in the journal Science Advances.
