If your on mobile and can’t find one of these guys start the tame equus pursuit and walk or fly around the island and eventually a arrow will show up on the top left of your screen. If you follow that then you will find an equus or two. Upvoote if you found this helpful.

When taming the equus on Xbox One, when it says to use the E button, you must press Y for it to feed when it bucks.

I had a hard time with this

Only one unicorn Equus can exist at a time in a world, so start looking!

Put this higher !!So if you play mobile I found 3 in the same spot okay so first do the volcano pursuit the one where it's the cave inside the pursuit should be south of the equator and in that general area if you look around you'll find them

They spawn more at redwood forest with Rexs, Raptors and carnos around....do they even know fear?

I saw a unicorn once stupid sabertooths

Can't find them? Grab your coconut shells and occasionally shout 'Ni!' - you'll find one before long

found a really pretty equus after searching for days and i was 3 berries short.

If your looking for these guys, I don't know if it's a guaranteed spawn but if you look around the rivers around the green obelisk, they seem to spawn to up to groups of three. I've tamed two from that same area, but be careful. That area has rexes, carnos, spinos, and allos, so bring something that can kill them. If you can't find any equus, just clear out the area. Also not about equus, but ovis can spawn here as well. I found two of them here in the jungle...
