Overview
Known from fragmentary remains including femur pieces, teeth, and finger bones from the Lukeino Formation in Kenya. The femoral morphology, particularly the distribution of cortical bone, suggests early bipedalism, making it one of the earliest potential hominins. However, its exact phylogenetic position remains debated.
Key Fossils
BAR 1002'00 (femur fragments), teeth, finger bones
