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.

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

They prefer cooked meat over raw. Don't waste your precious raw mutton, better cook it, as it tames faster and with higher efficiency.

Shoot it out of its tree, then pick with argie and drop it into a trap/hole. Cook up some mutton beforehand.
Bred a slick navy blue and silver mutation.
Many surfaces are considered 'vertical' for it to climb, including the southern side of Volcano on The Island, from which you can then pounce back into the redwood, which is the biggest leap I've found yet
