That's true, generally. But Late Cretaceous dinosaurs were united by many similar imperatives. According to the data I have been able to access (Graham Worth's data base) over 90% of late K dinos were larger than ostriches (from memory, now).
Does this include avian dinosaurs - enantiornithines etc.
And what do you mean by "larger"?
