The ancient conch shell was discovered at the site of some cave art in the French Pyrenees back in 1931, when archaeologists figured it must have been some sort of ceremonial cup. Now researchers using CT scans have determined that the shell was decorated and that its two holes had to have been man-made, most likely to accommodate a mouthpiece. They’ve managed to get three notes from the shell even without any mouthpiece (sound clip included). – Wired
