Dont go craggs island on mobile. Unless u have a rex, raptors will shred ur Spinosaurus and leave ur armor damaged. Thank goodness that for some reason pteranadons can take on high level raptors when u are taming the Spinosaurus. Ugh. Actually, dont tame on craggs island period. Unless its something that raptors dont agro on.
I had a Spino once. His name was J.J. I loved him. But like always, good things always come to an end. We were out looking for giant turtles for their keratin when J.J. fell over the edge of a cliff. I was on my pteradon so I flew over the edge and J.J. was following me back to bace when he was killed my a therizinosaurus... I just sat there on my pteradon watching him be torn apart, unable to help... So now, my bace is called Fort J.J. in honor of him. I will always remember my most loyal friend.
Whenever you're taking the Spino, remember to take at the very least 300 narcotics. It wakes up FAST, and whenever your taming ANY creature, surround it with wooden spike walls! Saves me countless tames from smaller pack animals. And to knock it, you simply need steep high ground and go to town with your tranqs. Happy taming!
I saw a tip saying they can't be tamed underwater because they will drown. I don't think that's true. I'm currently taming one that's fully submerged, it's at 60% and full oxygen. Only about 3ft of his dorsal spines are above water. :)
