Fly around on an argie while holding a parasaur on turret mode, the parasaur will sense it but make sure the thylacoleo can't reach you by flying high above so it hits the parasaur rather than you.

Stood on a rock and knocked it out with tranq arrows. No issues.

Tip: Starve tame it, use a bat to keep it unconscious and heal with owl when needed.

P.S once you put food on it you have to use narcotics/berries to keep it unconscious.

The redwoods are now basically a no fly zone, I lost a quetz, and a pter to these bastards. They jump out of the tree, rip you off your mount, and then pin you and your mastercraft armor to the ground and murder you.

They want titanoboa egg kibble and they prefer the cooked variants rather than the raw variants and it’s more efficient if you build a trap and shoot it with tranq darts
