Teeth ID requested

[Ruger9a]

Can anyone help identify these fossil teeth?  One was in a section of matrix from Nebraska and the others came from sections of matrix from the Badlands of South Dakota.

Looks quite similar to modern opossum dentition, 

But I am not an expert in these more recent fossils

I don't think it's a modern opossum.  For comparison:

Raccoon?

Thank you guys!!!!!  The photos match with the specimens I found on line do to your help.  The other photos I tried to post yesterday are show below.  They came from one of the same chunks of matrix as the Hesperocyon.  I didn't finish posting them yesterday due to the limit.  Or they the from the same animal or another?

These look like Mesohippus/Miohippus. Oligocene 3-toed horse.

Thanks rfarrar,  These jaw sections were in some matrixes with Oreodont skull fragments.  When I prepped the Oreodonts I kept all the larger 1-2" pieces of matrix in a box so I could search them if I needed some smaller missing pieces.  If I didn't need any additional pieces or the skulls were missing too many sections I would grab a few pieces of matrix and search them for any additional fossils.  Most had nothing, but once in a while...…….
