All this assumes Chiroptera and Rodentia are somehow comparable. Somehow "on 
the same level". <grin>

As to the actual question... I'm sure pterosaurs were a lot more diverse 
than the few fossils we now know. For example, the Anurognathidae are only 
known from the very best of fossil sites. This probably is why they are only 
known from Europe and Asia (I wonder if the Crato and Santana Formations 
will deliver one) and why they aren't known after the middle Early 
Cretaceous. Still, I don't think they were as diverse as birds today. For 
example there don't seem to have been any grain-eating species.
