I built a 2×2 foundation surrounded by walls. Snatched a baryonyx with argentavis and drop him in it. Was easy to tame for me.
Baryonyx
The Baryonyx is a large crocodile-like predator. While it might lack in attack power, its ability to swim extremtly fast makes it a fierce opponent — especially with its ability to travel on both land and in water.

How ARK players tame and knock out the Baryonyx: what to feed it, what to knock it out with, and how to keep it safe.
