Quote from source:

Four-legged creatures were mucking around a muddy basin in what is now Poland about 397 million years ago. And they left behind distinctive footprints, which have turned back the clock on the evolution of these landlubbers.

Scientists discovered the fossilized prints, which included various trackways and isolated prints, in the Holy Cross Mountains in southeastern Poland. Analyses suggest most if not all of them came from different tetrapod species — which are four-legged animals that had backbones, such as amphibians — with some possibly belonging to juveniles and adults of the same species.

The land creatures likely had bodies shaped somewhat like crocodiles, with fin-like tails and stumpy legs. And some of them were pretty big, reaching up to about 10 feet (3 meters) in length, the researchers said.


So almost 400 Million years ago our ancient ancestors were coming out of the water. What interests me is how the hell did they find 400 million year old footprints? It's interesting and again another evolutionary step in understanding it better...

Any thoughts?
