Dont listen to all this crappy "trap it in a stone trap that's way to expensive"all you need is a tanky dino and tranq darts/arrows and shoot it off the back of your dino but beware they have quite a bit of torpor and run when their torpor gets high (lost about 2 high levels like that and about 170 tranqs)so make sure you get them stuck up against a cliff or something.this is how I downed a lvl 150 near base.happy taming!! (:
The only dino that'll agro an unconscious paracer is a Rex. So if those are taken care off and your cautious about not bringing in extra friend with you. You don't have to worry about other creature damaging your tame.
I had a primitive bow and 47 tranq arrows in a swamp, and I had found a herd of there buggers. I picked a level 10 and ran around shooting it. I chased it around the swamp for a while(it was REALLY hard to dodge the kaprosuchus) and FINALLY knocked it out. After that, I shoved some mejoberrys down its throat and waited... Waited... WAITED for like half an hour until... BAM TAME.
These are great pets, animals don't want anything to do with you, with a long neck, everything comes after you. So my brother and dad went to the red wood forest with one of these and they were trying to tame a thylocoleo and NOT ONE even tried to attack them, they had to spawn cheat one instead, also these animals have amazing health
