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.
Easiest way to tame: make a dino pen, pick one up with an argy, put it in the dino pen then follow along with a basic taming process (knock it out, feed it). Make sure you have lots of narcotics on you!
Best thing about them: they can climb up really steep hills and they can potentially do lots of damage and can be fast.
Where to find: most commonly found on trees (they will be hanging upside down, high up on large trees) in the redwood forest areas (mainly on The Center) or I find lots of them in the Ragnorok desert.
I tamed one yesterday and found it really exciting. It’s not actually that hard.
1. Get on any flyer that can pick them up (wyvern recommended)
2. Search for a thylacoleo
3.when found pick it up and bring back to your taking pen.
4. Shoot it with tranqs until it knocks out
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
If your on Ragnarok, I suggest taming them in the desert, in my opinion its alot less dangerous b/c the thylas are on the ground. Make sure to go on a flying mount and watch out for rock golems and other bugs. The thylas are near the bottom of the desert.
