      Possibly in the sense that the absence of large 
terrestrial vertebrates on the Paleozoic was an unexploited niche: 
nothing had ever "thought" of evolving in that direction before, to 
horribly anthropomorphise evolution. 
     Can anyone give first-hand observations of where swans do most of 
thier feeding?
     P.S.: I'm looking for the holotype catalogue number and as many other 
specimen numbers as I can find for _Shunosaurus_.
