If you are taming an anky use a scorpion to ride and a cross bow as the scorpion allows u to shoot from on top and it is fast plus if u run out of arrows u can go in with the scorpion to finish the knock out.
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.
