Don't be like me, I waited hours looking for an Equus on my island. It was pain. Even on the Equus Spawns. I checked, checked a different spawn, came back, no Equus. I recommend for mobile players, go to redwoods, on the < left side where a mountain is at. Just wait a few minutes and 3 Equuses will spawn. If all three got killed, wait 1-2 Ark Days and come back to that same moutainous spot. 3 Equuses may spawn. But be careful and make sure to wipe predators out. Rexes, and huge raptor packs have a reputation to spawn. So be careful, and If you have an argy I recommend taking the equus out of redwoods.
