I took a short trip to herbivore island on my raft bearing tranqs narcotic and carrots I tamed an anky but then the question became how do I get it back to base so i put on the saddle rode on to my raft and came home with the new anky
1. Get tranq arrows and a crossbow
2. Find an anky of your desire
3. Shoot it in the head while walking backwards (they're slow so you can just walk while shooting)
4. When it runs away chase after it and shoot it
5. It'll be knocked out.
6. Feed it recommend food and any narcos if needed.
They get about 3x more metal than you! And depending on the level they can easily kill Raptors and other small predators.
They're found almost everywhere
Beaches, highlands, chalk hills, green forest, I've even see some near desert.
