What killed the dinosaurs?

I like Frank Wilson's commentary on this, by the way.

But if you follow the link in his post you'll read about a new book called What Bugged the Dinosaurs?: Insects, Disease, and Death in the Cretaceous, by George O. Poinar, Jr and Roberta Poinar.

Oregon State University press release on the authors and their theories here.

Added: Phil at Brandywine Books recommends a dinosaur book for kids, Encyclopedia Prehistorica Dinosaurs: The Definitive Pop-Up. I list it here because he notes that he has problems with the section on why the dinosaurs died.
