Dino info help!

I'm begging for recs as to the best sites with information about dinosaurs (yes it's for a fic, how did you guess?). I know I can stick "dinosaurs" into google, but I'm really not sure as to the quality of what I'll find.

Please bear in mind that (although I'm fine on how an archeological dig is run) the last time I read anything about dinos was when I was about seven.

I would really appreciate any advice I can get on this. Thanks.

EDIT:
Right, I've tried to look around. What I'd really like as a starting point, if anyone knows where to find one, is a timeline of what lived when during the Cretaceous Era.
