tyrannosaur species overlap in NA on turkey-day

As (hopefully) most of us sit down today for a nice big dinner of 
avian-dinosaur 'n' cranberry sauce,
I was wondering what is known of what species of tyrannosaurs were alive at the 
same time(s) in
North America - i.e., was Daspleto still around when Rex appeared, etc.?
