Well, strictly there is no evidence against spitting Dilo's. There is evidence against that frill, though.

I also think that fear of realism is the real reason behind all this. The continuity problem is easy to solve. They also didn't put feathers on Troodon in JP:TG. Neither did they showed Lady Margaret as a Torosaurus.
