What is "lomekwi"

Lomekwi is the name of three archaeological sites in Kenya where ancient stone tools have been discovered. Recent finds at Lomekwi site 3 (LOM3) are thought possibly to date to 3.3 million years ago, which, if confirmed, would make them the oldest ever found.

The two first sites were reported in the March 22, 2001 issue of Nature, and in the December 2002 edition of the Journal of Human Evolution.
