The Pseudodon shell DUB1006-fLorPseudodon DUB1006-fL (540,000-430,000 BP) is a fossil freshwater shellofPseudodon vondembuschianus trinilensis found at Trinil, Java, Indonesia. The shell has a zigzag engraving supposedly made by Homo erectus, which could be the oldest known anthropogenic engraving in the world.[1]
Geometric engravings on the shell DUB1006-fL were discovered by a biologist Josephine Joordens (then at Leiden University) and her colleagues in 2014. Their analysis suggests that the engravings are made by Homo erectus between 540,000 and 430,000 BP. The engravings were probably made on a fresh shell specimen using a shark tooth. It is also suggested that all grooves were made by a single individual in a single session with the same tool.[1]
Joordens et al. do not give a direct interpretation of the engravings, but suggest that "engraving abstract patterns was in the realm of AsianHomo erectuscognition and neuromotor control."[1] In her interview, Joordens says that since the intentions of the individual who made the engravings are not known, it is not possible to classify these engravings as art.[2] "It could have been to impress his girlfriend, or to doodle a bit, or to mark the shell as his own property," says Joordens.[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). Commentators of the original study by Joordens et al.[1] suggest their opinions, but do not study the engravings explicitly. Some commentators, similarly to the authors of the study, give a neutral description of the engravings, calling them a "doodle"[2] or "decorative marks".[3] Some other commentators suggest explicitly that these engravings are art.[4][5][6]
Tsion Avital, a philosopher of art and culture, makes a distinction between art and design and suggests that the engraving on Pseudodon DUB1006-fL cannot be seen as the former, but can well be the latter. He contests the description of the engraving by Joordens et al. who called it an "abstract pattern", saying that the terms "abstract" and "pattern" "hint obliquely at the possibility that these engravings possess some symbolic significance." "These engravings are in no sense abstract but rather are completely concrete marks," says Avital.[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.[8]
