Kenya Footprints Show 8 Paranthropus Boisei Traveled Together at 1.8 Meters

Eight 1.4-million-year-old footprints at an ancient Kenyan lakeshore appear to record adult Paranthropus boisei moving together, offering rare direct evidence of group behavior in an extinct hominin.
Some tracks indicate individuals up to 1.8 meters tall and about 75 kilograms, challenging earlier reconstructions that placed the species well below Homo erectus in body size.
Researchers assigned the prints to Paranthropus boisei using a 2024 method that compares foot shape and gait, separating them from Homo erectus tracks previously found on nearby ancient surfaces.
The apparent absence of juveniles and females suggests a mostly male group, though scientists say the tracks capture only a brief moment and cannot prove a stable social structure.
More than six East Turkana sites now preserve hundreds of hominin footprints, turning ancient lakeshores into an unusually detailed record of movement, habitat use and coexistence over 100,000 years.
