That page could probably use a minor update. The "quest mounts" page has the raptor is on there, but its at the bottom of the page called out by name(horned mountain saliraptor) and not specifically highlighted toward the top. The general mount page has them sorted into categories, and if you dont know what youre looking for it could take a minute to figure out.
As for other mounts, there are many. Every starting area(feydark, timorous, darklight and frostfang) has a horse mount(they all look different too) to be earned. If you follow the quest lines from the start and go long enough the mount will be yours naturally. The quests for these are normally right around level 13 or so. As i pointed out above, hoverpads can be earned at level 1 if the city fair is active(though, quest xp and exploration xp will probably be enough to push you to level 3 or 4, even if youve done nothing else).
As for non-ground mounts, the raptors are available at level 30 in butchersblock, as you discovered. There are gliding komodo mounts at level 60 to be found in tenebrous tangle. And the flying griffin mounts arrive at level 85 in great divide(the quest to grant a fae or arasai true flight is also level 85, and located not too far away if memory serves). There are also crafter versions of all these mounts available from roughly the same places(often standing just a few feet away), though the crafter packhorse comes from a butchersblock crafting quest.
Later on you can find carpet mounts(sinking sands quest), cloud mounts(general overrealm quest series), warg mounts(loping plains quest series), rhino mounts(fens of nathsar quest series), a timber wolf mount(great divide quest series), almost all(possibly all) of the in game holiday festivals have an associated mount that can be quested for or bought, plus there are dozens and dozens of variations on these overall themes available to be purchased in various cities and on various factions. Also there are plenty of vanity mounts on the marketplace(i think of them this way since theyre mostly just special looking versions of other mounts you can already get, usually with minor stat boosts), and pretty much every booster set of cards for the legends of norath game has a chance of a mount appearing as a loot card(though this is likely the most frustrating way to try getting a mount, as loot cards are random and somewhat rare).
In the end, thats a lot of mounts to choose from.
