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
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.
The best way to tame one of these dudes (on mobile) is with a trap How you make the trap is by place it 3 normal gates no doors then lure one in by punching shooting or agrouing it in anyway then once it is in side of those put gate behind it so it is trapped then tranq away.
