Dallasaurus turneri: Mosasaur Missing Link

This is very, very cool. Sixteen years ago an amature fossil finder Van Turner found a fossilized Mosasaur. Why is this particular Mosasaur, Dallasaurus turneri, so cool? Well, it turns out that this Mosasaur still has its legs. It is a clear transitional fossil from a land based reptile to the water based reptile most are familiar with. Dallasaurus was also abot 3 feet long, compared to the Mosasaurs at the end of the Cretaceous that were around 40 feet long.

    Balderdash! This so-called “Moasaur” was clearly a serpent that helped the main serpent trick Eve in the Garden of Eden, but wasn’t directly responsible for it. So God gave him stubby little legs instead of taking them away completely.

    (Actually, it turns out the serpent’s leg status is a matter of heated debate.)

    There is no doubt in my mind that this is a picture of the offspring of a Muskie and amphibian known in the south as a Hellbender.
    Instead of hunger pangs the Muskie, pumped up after eating a bottle of blue triangle shaped pills dropped from ted Kennedy’s boat, simply sidled up to the Hellbender and happened to get lucky. Do I know my science or not?

    Personally I think it should have been given a Scotch name, in honor of TK of course!
