Eleven early humans, recognized as advanced members of the species Homo erectus and popularly known as Solo Man (from their grave site on a bank of the Solo River near the village of Ngandong in eastern Java, Indonesia), may have been the victims of cannibalistic activities.

Homo erectus soloensis, formerly classified as Homo sapiens soloensis, is generally now regarded as a subspecies of the extinct hominin, Homo erectus.

The only known specimens of this anomalous hominid were retrieved from sites along the Bengawan Solo River, on the Indonesian island of Java.

The remains are also commonly referred to as Ngandong, after the village near where they were first recovered.

Though its morphology was, for the most part, typical of Homo erectus, its culture was unusually advanced.

While most subspecies of Homo erectus disappeared from the fossil record roughly four hundred thousand years ago, H. e. soloensis persisted up until fifty thousand years ago in regions of Java and was possibly absorbed—or consumed—by a local Homo sapiens population at the time of its decline.
