This is a way to tame a baryonyx, pretty simple.

1. Make 3 stone gateways with the gates.

2. Make the bear trap in it

3. Lure the baryonyx into the trap.

4. Then put the gateways and the gate.

5. Wait for it to starve.

6. Feed it! It will eat the food fast if it starves.

There you go! If it doesn’t work you may use other tips or try using your own.
