How about these (not to scale):
Orohippus, 52-45 MYA
Mesohippus, 37-32 MYA
Miohippus, 32-25 MYA
Parahippus, 24 -17 MYA
Pliohippus 12-6 MYA
Equus, 5 MYA-present

Thanks for the pictures. But that doesn't look to be any more variation then has happened to the dog, in the last 150 years or whatever. Compare a great dane to a teacup poodle -- the bones you list don't appear to me to provide evidence of anything other then variation within a kind (which I already know is true. I grew up on a farm.)
Is that really all the change there was in 45 million years? No more then intentional dog variation in 150 years?
But the sort of "yet undiscovered intermediate fossils" which I was talking about are the sort that get from dog to horse, and from fish to dog. There are certainly lots of fossils from each group, but what's lacking is the fossils that build a fine chain from one group to another.

PS: Also let us not forget that the shape of these skeletons and their posture has been somewhat influenced by the preconceptions of the people who pinned them all back together. I'm not saying they did it wrong just that we need to remember that a person, who never saw the animal alive, did pin them together.
How about these, to scale:

Micro-evolution in short time periods can produce some very drastic changes.
