Mata Menge is an early Middle Pleistocene paleoanthropological site located in the Ola Bula Formation in the So'a Basin on the island of Flores, Indonesia.

[7] The fossil remains of Stegodon florensis, Hooijeromys [nl], Varanus komodoensis, crocodile, various birds[10] and freshwater mollusks were also unearthed, from both fossil-bearing intervals at Mata Menge.

[13] Evidence from Mata Menge suggests that the area saw much volcanic activity that has affected items found at the excavation sites over the years.

During successive excavations at Mata Menge, principal investigator Gert van den Bergh and colleagues determined that fluvial fossil-bearing Layer II of the site was covered by a more than 6 m thick interval of clay-rich mudflow deposits.

[9][8] The artifacts, faunal remains, including those being hominin in origin are believed to have been exposed at the surface for some time due to evidence of weathering, before then, being moved by a small stream and subsequently rapidly covered by a succession of mud flows overtime.

[9][8] These mudflows may have been caused by volcanic activity inside the Welas Caldera to the north of Mata Menge, in which a lake had formed.
