     Has anyone ever suggested the possibility of an oxpecker-like
pterosaur, eating insects off the backs of dinosaurs?
     I can easily imagine that dinosaurs would have welcomed oxpecker-like
birds cleaning their skin of parasites, but I wonder if an insectivorous
pterosaur might have ever evolved to fill a similar niche.  Wouldn't
procumbent teeth work well for feeding on skin parasites?  Just a thought.
