Not to be rude, but I have to say I think this is very unlikely, for two main 
reasons:  first, dinosaurs and angiosperms coexisted quite well for tens of 
millions of years (at least 60 million); second, there remain to this day 
vast ecosystems dominated, at least as far as the large tree niche is 
concerned, by gymnosperms.
