You can find them very easily, in Scorched Earth. Just go near mountains, and look for the Thylacoleos with a Spyglass. Then, get up on a nearby rock. Try to shoot them, because unlike when you’re riding them, they don’t climb up to attack you. They will just stand at the bottom of the rock, so then you will be able to get many Tranq Arrows into him. (Crossbow is better than Bow.) After you tranq the Thylacoleo, you should place a Campfire and cook some meat, because Cooked Meat is actually better to use than Raw Meat. To craft a Thylacoleo Saddle, you need 20 Metal Bars, and around 250 Hide, and 200 Fiber, so you should keep an Argentavis with you, because they might Server very useful. Then, you just Tamed a Thylacoleo!
It all started when I played ark for the first time, I had managed to tame a high level tapejara and absolutely love him. I named him Barry and we set off on many adventure exploring the island. On day I was just flying through the redwoods and usual taunting the carnivores below me for not being able to touch me. BAM the thylacolia jumped out the trees and ripped me off Barry. Barry was whistled on nuetral and as he came down to aid me a desperately tried to get him on passive, but I was panicking, my screen shook as I was terrified as this was my first encounter of one. I tried to punch it but I inevitably died. I respawned and immediately got on my pteradon but just as I got on the saw the message in big red letters that Barry had fallen to the thylacoleo.
The redwoods are now basically a no fly zone, I lost a quetz, and a pter to these b******s. 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.
I was set off on a mission to find Bigfoot with my level 83 Argy I had, as I was soaring through the redwood forest BAM 2 of these beasts jumped at me both level 140 and ripped me off of Argy and I couldn’t tell you how much it scared me but luckily my double barrel and Argy could kill them both leaving me one shot. So yeah DONT FLY IN REDWOODS
They will jump on you and murder you even if you're on a fricking wyvern. You are not safe from them no matter what animal you have. Just accept your slow and tender death. I learned it the hard way lmao. Scared the fckng hell out of me
Wanna find one? Simply mind your own business flying through the redwoods and they'll find you! Just make sure you can take some fall damage and that your tame is set to passive so it doesnt kill the thyla. (I know this seems like a joke but this is legit the only way I know how to find them.)
