The Little Tetrapod That Could: Acanthostega (SD Followup)

A tetrapod is a four-legger and such a creature is all the more remarkable when there were no tetrapods previously and that's why the interest in Acanthostega.  He's extremely close to the first creature which came out of the water onto land and that 'living submarine' effect is one of the greatest biological transitions ever to take place on the planet.  (Science Daily:  Life history of the 360-million-year-old tetrapod Acanthostega rewrites the tetrapod move to land)

Here's a pic of a sample fossil specimen:


What I get from that other than not very much is being a fossil hunter must be such a massive bitch when this one is in at least eight pieces.


Here's an artist's visualization and he's about two-feet long:


If you got the required kid's time poking around in creeks and ponds while avoiding being bitten by a snapping turtle, you have probably seen a creature of this nature but this one is from three hundred and sixty million years ago and he doesn't even exist anymore.  There was a question of which creature is most likely to have come out on land first and this one looks like your Huckleberry, according to their science.


Please, forgiveness in advance, as this creature is the Martin Luther King of lizards, man.  He climbed out of the water for the first time to find the Promised Land and I've been to the mountain top.  I mean no disrespect whatsoever as these were incredibly brave things and it may well have started for every land-based creature in this little slimy snapper right here.
