4 mammal teeth ID

[The Dude]

Hello again everyone!

4 teeth in 2 hours out of my spot in the Peace river, Florida. part of the Bone Vally formation.

The first one (far left I am pretty sure its a nice horse tooth. The second (curved) could also be a horse toothbut has these 3 "ribs" (second pic) I guess you would call them that make me think it could be something else. The 3rd from the left I think another horse tooth just broken and the far right, I have no idea. Thought maybe a dolphin but I looked at pictures and the ones I seen dont have 2 roots like this one. Perhaps a mammal of some kind. Excited as always to hear what you think, thank you! 

The far left tooth is approximately 2" (50mm) this should be good reference for the others.

I believe your first three are horse.  The last I hesitate to make a guess.  A photo straight down on the bite surface could help others make a positive ID.
