Classified as the Pseudodon shell DUB1006-fL, was discovered by Josephine Joordens in 2014.
The shell was recovered from the Pleistocene soil layer at the Trinil site Java, Indonesia.
The shell, supposedly made by Homo erectus, could be the oldest known anthropogenic engravings in the world.
Over half a million years ago, expression in symbology may have already existed in hominids.
