Pseudodon shell DUB1006-fL

The assemblage, including the shell DUB1006-fL, is now at the Naturalis Biodiversity Center, Leiden, Netherlands.

Geometric engravings on the shell DUB1006-fL were discovered by a biologist Josephine Joordens (then at Leiden University) and her colleagues in 2014.

[2] The main discussion happens around the question of whether the engraving on the shell can be considered as art (which would make it the earliest known artistic expression of hominids in the world).

Some commentators, similarly to the authors of the study, give a neutral description of the engravings, calling them a "doodle"[2] or "decorative marks".

[7] The Indonesian government has requested the return of the complete Dubois collection (circa 40.000 fossils), because they regard it as goods that were looted by the Dutch during the colonial occupation.
