Muddy footprints found beside Lake Turkana, Kenya reveal two ancient hominin species were once neighbors 1.5 million years ago.

About 1.5 million years ago, individuals of two different species in the human evolutionary lineage trudged on a muddy lakeshore in northern Kenya, leaving behind intersecting trackways alongside the footprints of antelopes,

The footprints were left in the mud by two different species “within a matter of hours, or at most days,” a co-author of the research study said.

Footprints from 1.5mil years ago made by two different species of human ancestors were made within hours on the same spot—a fossil first.

Study provides first evidence of different bipedalism styles on same footprint surface, attributed to both species.

Researchers discovered 1.5-million-year-old footprints in Kenya's Turkana Basin, revealing coexistence of Paranthropus boisei and Homo erectus. The prints, showing distinct walking patterns, provide direct evidence of the two species' interaction and environment,

Newly discovered fossil footprints indicate two different ancient human relatives walked upright around a muddy lake in Kenya.

A discovery in northern Kenya hints that two extinct species that were our ancient relatives shared the same habitat and possibly interacted.

Pictured above is a fossil footprint believed to have been created by a hominin species known as Paranthropus boisei, one of 12 such footprints unearthed in Kenya that date back 1.5 million years. The dig took place in 2022, when Hatala and his colleagues ...

Scientists discovered fossilized footprints along Lake Turkana, Kenya, revealing that early human ancestors Homo erectus and Paranthropus boisei coexisted around 1.5 million years ago. The distinct footprints show different walking styles,
