No, sharks suffered tremendously. They survived as a clade, but the
diversity in that clade dropped significantly. Of course, if we make
the not unreasonable assumption that a number of species evolved in
tandem with inland seas, the regression of said seas would result in a
lot of dead sharks. They wouldn't, of course, even notice an asteroid
(unless they happened to be skimming the surface that day).
