Scientists have found traces of an unidentified hominid 3.7 million years old. This is reported by journal Nature.

When researchers found ancient footprints in Tanzania in soft volcanic ash, which later turned into rock, they thought they were left by a bear that walked on two legs. Further investigation revealed that they were in fact left behind by an extinct human species. The study authors note that the gait of this hominid was very unusual. He walked with his legs crossed, as New Scientist notes, this gait, albeit in an exaggerated form, but resembles the one used by the models during the walk on the catwalk.

What kind of hominins left their prints is unknown. The authors of the new study note that they do not match other sets of footprints at Laetoli, Tanzania, so they were likely made by a different species. If true, this would mean that two species of hominins coexisted in the same region at the same time.

Recall that Laetoli is an area in Tanzania, 20 km from the Sadiman volcano, where foot prints of erect hominids were discovered in 1978, who lived about 3.6 million years ago. Also in the region, another group of scientists found footprints of Afar Australopithecines – a genus of fossil great apes that had signs of upright walking and anthropoid features in the structure of the skull.
