Its significance lies in the dot-like markings inside the shell. The scientists have identified the deliberate modifications that would have enhanced the shell's ability to make sound. The Upper Palaeolithic people who owned the shell were part of what archaeologists call the Magdalenian tradition, which was notable for its particular approach to tool-making and use of bone, antler and ivory.
Why do seashells sound like the ocean?
Image source, Carole Fritz. There is a bison picture, for example, traced out by finger dots. These patterns, made with an iron oxide pigment red ochre , take the form of fingerprints. It's also known that the communities of the Pyrenees would interact with similar communities in the Cantabria region of coastal northern Spain. Image processing enhancements were used to study the patterns painted on the inner-surface of the shell's opening.
Listen to the sound of the conch shell horn. Archaeology France Pyrenees Music. The conch therefore reinforces this relationship.
An example of a New Zealand conch with its mouthpiece made of a decorated bone tube. These match the artwork on the walls of the Marsoulas cave in the Pyrenees where the artefact was unearthed in The shell measures 31cm in its longest dimension, and 18cm at its widest. By Jonathan Amos. When the s excavators at Marsoulas first looked at the shell, they thought it nothing more than a ceremonial drinking cup.

These include the hole excised at one end that would have permitted the insertion of some kind of mouthpiece, and cuts at the other end that would have made it easier to insert a hand to modulate the sound - in the same way a French horn player might insert their hand into the bell of the instrument to alter the pitch. It was once home to a living organism, of course; most likely a species of cold-water Atlantic sea snail called Charonia lampas.
The artefact is the oldest known wind instrument of its type. The discovery is reported in the journal Science Advances.

Archaeologists have managed to get near-perfect notes out of a musical instrument that's more than 17, years old. To date, only bone flutes can claim a deeper heritage. It's a conch shell that was found in a hunter-gatherer cave in southern France.
The team asked a professional musician to blow into the conch, and to their delight he was able to generate notes close to C, C-sharp and D. And the sound is very directed in the axis of the aperture of the shell," said Philippe Walter from Sorbonne University. Related Topics.

The researchers have produced a 3D printed replica of the shell so they can further explore the musical possibilities of the conch without the risk of damaging the original artefact. The shell once belonged to a large sea snail of the species Charonia lampas. The shell must have been a prized object because the coastline where it was presumably picked up or traded is more than km away.
