Human footprints stir the imagination. They invite you to follow, to guess what someone was doing and where they were going. Fossilized footprints preserved in rock do the same—they record instances in the lives of many different extinct organisms,

Smithsonian: Fossil Footprints Reveal That Two Early Human Relatives Lived on the Same Landscape in Kenya 1.5 Million Years Ago

A 1.5-million-year-old lakebed from Kenya shows two ancient human relatives cohabitating an environment, shaking up our ancestors' story.

Two sets of fossilized footprints from early human species were made within a few hours of each other about 1.5 million years ago, researchers suggest

The researchers believe the footprints were made within hours of each other on the shores of an ancient lake in present-day Kenya.

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,

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,

A set of footprints found at the site of Koobi Fora in Kenya reveals that our ancestor Homo erectus coexisted with a now-extinct bipedal hominin, Paranthropus boisei, 1.5 million years ago.

Muddy footprints left on a Kenyan lakeside suggest two of our early human ancestors were neighbors some 1.5 million years ago.

In fact, the footprints indicate these two species were walking along the lakeshore within hours or days of each other, according to a study published this week in Science that Feibel co-authored. “You can never tie down where bones come from [because] they could be transported or carried off by carnivores or scavengers,
