Re: More nose thoughts

The closest I can come up with is the already mentioned 
Komodo Dragon (Varanus komodoensis) and the Aldabra 
Tortoise (Geochelone gigantea), both of which have external 
nares that extend back above and slightly in front of the 
orbit (back toward the "forehead" as it were).  Both also 
have fleshy nostrils at the front. Not nearly as extreme as 
in the mammalian examples, but it's something.
