Again these are technically their robot modes, not their alt modes. And in recent Neo-G1 media their robot modes have been portrayed as looking more Cybertronian.
Cybertronian Ratbat
Cybertronian Ravage

We've never seen what Turbofoxes (or Petrorabbits) look like... so who knows. But just because they're called foxes doesn't necessarily mean they have to resemble foxes. After all, Firefoxes (aka Red Pandas) are neither foxes nor bears and are more closely related to raccoons, weasels and skunks (Ailuridae family).

I'd buy that theory. Grimlock would need to have contact with some place that has saurians on it in order for him to adapt his alt mode to resemble one. I'd sooner believe that there are T-Rex-like saurians on Animatron than on Cybertron.
