"There was still room for innovation, though: for example, paleontologists believe that Stomatosuchus subsisted on plankton and krill, like a sperm whale!" :-)
Why does anyone bother about about.com? This is like complaining about YouTube comments. :o)
Full SIWOTI treatment: Yes, *Stomatosuchus* was at times thought to be possibly toothless, and then speculation ensued that it might "therefore" have been a filter feeder, like a... wait for it... baleen whale, but not only is all that wrong judging from *Laganosuchus*, it also never was such a consensus that "paleontologists believe" would have been an appropriate wording.
(SIWOTI means this: http://xkcd.com/386/ -- soon I'll gain the right to buy one of those T-shirts that say "I am aware of all Internet traditions".)
