Huge 1.5-Million-Year-Old Footprints Suggest a Human Cousin Nicknamed Nutcracker Man Was Far Bigger Than We Thought

New estimates from 21 footprints suggest the species was taller and heavier than once thought, and eight individuals moved together, researchers said.

  • Researchers identified 21 footprints made by eight Paranthropus boisei individuals near Kenya's Lake Turkana, according to a report published Monday in the journal PNAS suggesting the group traveled together about 1.4 million years ago.
  • Known as 'Nutcracker Man,' Paranthropus boisei inhabited eastern Africa from about 2.3 million to 1.2 million years ago, characterized by extremely robust skulls and large teeth adapted for tough vegetation.
  • Standing up to 6 feet tall and weighing as much as 165 pounds, P. boisei was more humanlike in size than previously estimated, according to updated calculations based on the footprints.
  • Lead study author Kevin Hatala, an associate professor of biology at Chatham University, said the tracks reveal complex social structures, with "the footprints may capture a group of adult males moving together along the lakeshore."
  • Although P. boisei died out around 1.2 million years ago amid climate change, these preserved prints provide a rare snapshot of how early hominins engaged with their environments and each other.

Fossilized footprints of about 1.4 million years found in northern Kenya are leading scientists to review what was known about Parantropus bonei, an extinct species of hominide known as "Man Nutcracker". Analysis of 21 brands preserved in the soil suggests that these ancient relatives of humans were significantly higher than previous estimates and presented a more complex social behavior, possibly forming groups composed only of adult males.
