Lava footprints in Italy over 300k years old.

The mysterious footprints are well known to those living near Roccamonfina, an extinct volcano in southern Italy that hasn't erupted in tens of thousands of years.

Since 2001, researchers have sought an explanation for the dozens of impressions left by a small group of human ancestors and

even a few animals snaking their way down the mountainside.

Now a new paper suggests some individuals were actually heading back up.

Over recent years numerous expeditions have provided detailed measurements on a total of 67 indentations left by the scuffle of feet, hands, and legs, all divided across three distinct tracks headed away from the mountain's summit.

Thanks to the latest contributions by a team of scientists from institutes across Italy, we now have details on a further 14 prints - these ones even larger than the others - some of which head up the mountain rather than down.

Radiometric and geological dating of the various rock strata have already established the imprints were cast in the soft blanket of ash left in the wake of an eruption that took place around 350,000 years ago, making them some of the oldest preserved human footprints on record. Full article here.

The article speculates these to be Neanderthal footprints, but they may be human.
