In HeartGold/SoulSilver you can find a Ryhorn on Victory Road or in the Safari Zone. In the Safari Zone, it's in 'savannah' areas.
You have to find them by chance. Walk around where they are and maybe you will find a shiny ryhorn.
Ryhorn evolves into Rydon at lv. 42. it will also learn Hammer Arm after it evolves.
you have to evolve a ryhorn from the safari zone
You indeed can, but you have to wait until you get all the badges, and Ryhorn will be on Victory road. I also think that if you evolve Aron twice, you'll get a Ryhorn. (Aron is in the cave in Dewford town.) Hope I helped! :)
It wasn't available until diamond and pearl, but you can find ryhorn it the safari which evolves into rydon
you can only get rhyhorns on route 227 or stark mountain (but it's really hard to find it.)
It evolves at lv.42
Ryhorn is not in any specific place in the Safari Zone. Just check around and search through the grass, and hope to find a Ryhorn. Ryhorn should be pretty easy to find in the first area you enter, though.
Rhyhorn evolves into Rhydon at Level 42
In HeartGold/SoulSilver you can find a Ryhorn on Victory Road or in the Safari Zone. In the Safari Zone, it's in 'savannah' areas.

You must have a protector which is located in Route 228, you must first evolve Ryhorn to Ryhdon at lvl 42 then give Ryhdon the protector to hold and then trade it with someone, trade it back and you'll get Ryperior.
Safari Zone(Encounter Rate is common)
You have to find them by chance. Walk around where they are and maybe you will find a shiny ryhorn.
