Buya or Buia is an archaeological site in the Danakil Depression of Eritrea.[1][2] It is known for the discovery of Madam Buya,[3] a one million-year-old fossil of a Homo erectus skull.[4] Two other expeditions in 2011 and 2012 also unearthed ancient hominid fossils at the site. Archaeologists have uncovered large quantities of animal fossils and lithic tools in the area.[5]
