Have they ever been defined phylogenetically? If not, I'd suggest replacements, perhaps something on the order of Osteophora ('bone bearers') for Osteichthyes and Sarcoscelidea ('fleshy limbs') for Sarcopterygia.
Or just "Ostei".
Most sarcopterygians do have wings or fins or flippers, though. :) -- T. Michael Keesey The Dinosauricon: http://dino.lm.com Parry & Carney: http://parryandcarney.com
