Homo luzonensis
The archaeologist who found the remains is Armand Mijares.  He had dug in Callao Cave in 2003, but he stopped at a little more than one meter deep.  He said that the discovery of Homo floresiensis, a hominin from about 50,000 BP found in Indonesia in 2004, led him to return to the cave in 2007. About a meter and a half below where he had stopped before, his team found fossil bones.  One of the bones was a human metatarsal, a foot bone.
