Underwater Flight

["Rob Gay" <rob_redwing@hotmail.com>]

Now, does this suppose that these theropods are already feathered when they 
enter the water? Because if they aren't, I see no pressure for them to 
evolve feathers, once aquatic. What made theropods special from, say, 
icthyosaurs and mosasaurs? They didn't evolve feathers. And animals with 
covering that spend most of their time in the water tend to reduce the size 
of their covering, both in length (penguin) and total area (cetaceans). It 
seems like the pressure in an aquatic environment is biased against the 
begining of flight.
Also, on the comment earlier about segnosaurs; if they were saurapodamorphs, 
even with their dino-fuzz, then what implications does this have for the 
origin of fuzz (is it a basal character, like mammal fur?), and what would 
this mean for BCF?
