A good way I found to find these is to go to the redwoods riding a parasaur and walk into the forest spamming the parasaur’s ability. It will alert you to a thylacoleo in a tree if there is one, just make sure to look up at the trees near you if it finds enemies. Also would recommend bring a dino or two to protect you and your parasaur. Just signal them to passive when you find your thylacoleo. Hope this helps.
