Pseudodon is a genus of bivalvia of the Unionidae family that is native to East and Southeast Asia. There are 14 recognized species.
Description
The taxon was described by
British Burma as a subgenus of the genus Anodon. Gould included two species in the taxon, the type species Anodon inoscularis and Anodon salweniana.[1]
The shell of Pseudodon is rather thick and shaped like an elongated oval, with a slightly convex crown on the upper valve shifted toward the rear.[2] The surface, although most often smooth, is in some species crossed by deep transverse furrows. The hinge teeth are high, thick, and rounded at the apices.[3]
Range
The habitat of the genus is limited to East and Southeast Asia, mainly the
Indochina.[5]

Pseudodon shell DUB1006-fL is a fossil shell of Pseudodon vondembuschianus trinilensis that was found in Trinil, Java, Indonesia. The shell has a zigzag pattern engraved on it by a Homo erectus. It was carved between 540,000 and 430,000 years before present, and is the oldest known anthropogenic carving in the world.[6] There is an ongoing controversy on whether or not the carving can qualify as art (which would make it the oldest piece of art in the world). Some commentators call it a "doodle"[7] or "decorative marks",[8] while others suggest that the carving is explicitly art.[9][10][11]
