Meganthropus is a name commonly given to several large jaw and skull fragments from Sangiran, Central Java, Indonesia. The original scientific name was Meganthropus palaeojavanicus, and while it is commonly considered invalid today, the genus name has survived as something of an informal nickname for the fossils.
As of 2005, the taxonomy and phylogeny for the specimens are still uncertain, although most paleoanthropologists consider them related to Homo erectus in some way. However, the names Homo palaeojavanicus and even Australopithecus palaeojavanicus are sometimes used as well, indicating the classification uncertainty. Of particular interest is that the finds were sometimes regarded as those of giants, although that is unsubstantiated.
After the discovery of a robust skull in Swartkrans in 1948 (SK48), the name Meganthropus africanus was briefly applied. However, that specimen is now formally known as Paranthropus robustus and the earlier name is a junior synonym.
Some of these finds were accompanied by evidence of tool use similar to that of Homo erectus. This is the reason it is often linked with that species.
