You have no way of backing that statement up.

There is nothing saying what form a Grimm can or can not take, real animals, fictional creatures, hell the Sabyrs and Megoliaths are prehistoric beings so why would Dinosaurs not be viable?

The Apathy were inspired by a creepy scarecrow Miles spotted and an old story he read.

I feel like they can take a number of forms.

True Dragons might be a no mainly because the Gods took those forms, but we have no confirmation on that point.
