'A Moment in Time': Fossil Footprints Shed New Light on the Extinct 'Nutcracker Man'
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.

'A moment in time': Fossil footprints shed new light on the extinct 'Nutcracker Man'
Did ancient footprints just rewrite the story of Nutcracker Man? New fossil tracks from Kenya suggest this extinct human relative was much taller and more social than scientists once believed
1.43 million years old footprints from Kenya appear to show a group of early human relatives. The prints provide new indications of physique, movement and social behavior.
In an ancient lakebed in the Nefud Desert in Saudi Arabia, 115,000-year-old footprints belonging to Homo sapiens have been unearthed. Surrounded by prehistoric animal tracks, the discovery could change what we know about the migration route of early humans from Africa to the rest of the world.
Ancient footprints found in Kenya reveal how early human relatives may have travelled and lived together 1.43 million years ago
Ancient footprints found in Kenya offer rare glimpses into early human relatives. These impressions date back approximately 1.43 million years to a lakeshore environment. The tracks suggest several large-bodied individuals moved together across muddy ground. This discovery provides new evidence about hominin body size and social organization. The findings reshape current ideas about Homo erectus and Paranthropus boisei.
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.
