I have, it's phony. The starting point of it is a re-classified and renamed skeleton from a hyrax, a totally different genus from the horse.
Furthermore, if evolution were to be true, the examples of gradual evolution in the fossil record should be the rule not the exception. An example or two of gradualism (even if they were valid) is not proof.
That is one problem with evolution. There's no way we'll ever find all of the fossils necessary to close up every little hole to make people like you happy. They'll probably find every fossil, documented evolution chains for millions of species, and you'll point to the one they can't find and say "That disproves your theory."
