Four-legged Creature's Footprints Force Evolution Rethink

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.

Maybe they are related to the llizard men. I would like to hear everyones opinion on this matter

I don't see where this will make anyone "rethink" evolution. Freshwater or salt, I don't see the difference.
While they posit that these animals went in to intertidal zones to find food it is also just as likely that they went into shallower waters to avoid predation. Generations of fish in very shallow waters eventually transformed their pectoral fins into feet to go in to even shallower waters. This would allow them increased food sources and to get even further away from predators.
There might also have been an ectothermic advantage in having a part of their bodies exposed to the sun, allowing them to move somewhat quicker during cold periods. That is my theory about the sailback dinosours (dimetrodon, et al) and it may apply to these creatures as well.

Evolution is such an amazing science. We have so much yet to learn. Thanks for the post, I love this kind of thing!

Nice find



S&F

Conclusion?
The only thing we know for sure is that we don t know enough...

As there's no evidence of Lizard Men ever existing, I'd say it's a fair bet this has nothing to do with them.
