What does it all mean?And a challenge:
It means that the neatly gift-wrapped correlation between stratigraphy and phylogeny, in which elpistostegids represent a transitional form in the swift evolution of tetrapods in the mid-Frasnian, is a cruel illusion. If – as the Polish footprints show – tetrapods already existed in the Eifelian, then an enormous evolutionary void has opened beneath our feet.
