Trinil Shell Engravings by Homo erectus
c. 540,000-430,000 BCE · Prehistoric
Between 540,000 and 430,000 BCE, Homo erectus at Trinil in Java, Indonesia created geometric engravings on freshwater mussel shells. Eugène Dubois excavated the shells in the 1890s. One shell contains a zig-zag pattern, and others show precisely drilled holes at muscle attachment points for food extraction. The engravings predate previously known examples by approximately 300,000 years and suggest Homo erectus possessed cognitive capabilities for abstract thinking and symbolic representation.
