Re: Prehistoric Plankton Predators (PPP for short)

oceans: Among the elasmobranchs we have the Whale Shark (Rhincodon typus)
the Basking Shark (Cetorhinus maximus) & the Megamouth Shark (Megachasma
pelagios) the various species of Mobula & Manta rays, (Mobula sp. & Manta 
sp.) The teleosts have provided us with the Ocean Sunfish (Mola sp.), and 
let's not forget the 10-13 species of Mysticete or baleen whales.>

  It is somewhat a likelihood that the large (~10m) croc *Stomatosuchus*
(= *Stromerosuchus*) from the Cenomanian of Egypt (Baharija Formation) was
planktonivorous, but it is found in paralic (mangrove) waters, not open
sea. *Stomatosuchus* is edentulous and the mandibles are widely separated
fro most of their length, providing a large, expansive gular pouch, with
long and wide jaws. This animal had an impressive gape.

  Little steps are often the hardest to take.  We are too used to making leaps 
in the face of adversity, that a simple skip is so hard to do.  We should all 
learn to walk soft, walk small, see the world around us rather than zoom by it.
