Shell tool use by early members of Homo erectus in Sangiran,
central Java, Indonesia: cut mark evidence

Abstract

Sangiran has been known as a source of fossil Homo erectus but is better
known for the absence of archaeological tools. Cut mark analysis of
Pleistocene mammalian fossils documents 18 cut marks inflicted by tools
of thick clamshell flakes on two bovid bones created during butchery at
the Pucangan Formation in Sangiran between 1.6 and 1.5 million years ago.
These cut marks document the use of the first tools in Sangiran and the
oldest evidence of shell tool use in the world.
