if you are playing mobile and you want to tame this dino I strongly recommend to use bio toxin rather than narcotics. bio toxin give 80 torpor while the narcotics give only 40, plus getting and finding a bio toxin is much more easier and convenient because you could just find those glowing jellyfish almost everywhere in the beach rather than harvesting and creating narcotics. Trust me Almost all of my carnivorous tames I only uses nio toxin
