Hippology would be the horsey equivalent of anthropology. Sorry it doesn't sound punnier.

Hmm, a very interesting premise, but I feel like it gives away too much too quickly. If I were you, I would have paced it out a lot more. Like, make the first chapter an unrelated study of thestral burial practices, which piques Uncovered Truth's curiosity. This leads him to dig deeper, before finally outfitting an expedition upon finding the legends of carnivorous ponies.
