I agree with this IDs.  except...

7, I also dont know, but I do not find these in the Lance or Hell Creek

8.  need more views.  Is this the one you showed in a separate post that I IDed as a mammal premolar?  

9, yes  these are the little cusps on the edge of the tooth

11... I think I see out of focus serration on this one.  Cool strange tooth indeed.  

 

Fun stuff.

Found a couple of pieces of small hadro teeth and small dino bone fragments, but no theropod.  Still have some more stuff to look through (really fine matrix though). Probably will get more matrix eventually (got 4 lbs to start).

 

There haven't been many complete descriptions of the fauna in Aguja, so the crocodilian teeth you have can be cf. Brachychampsa sp.

That makes me laugh as well.  Both of you have fun finding little things.

It looks like Columbusia. It has been identified as a Sclerorhynchiform by some and as an Orectolobiform by others.
