Tamed one of these in the northern half of the island, i got killed by a rex. I didn't have a base yet (singleplayer) so i went to Cragg's Island and built a base. I tried going to the place were i got killed, no sign of him. One week later, i was going to death island with my flyer. On the way there, i saw my lost baryonyx killing the rex who killed me. I got the barry to my base. 10/10 would die again.
Was out hunting Piranhas when I saw one of these. I screamed, ran, it stopped following me a long time before I reached my base. I still build large walls, placed traps everywhere, discovered she was a female, and shortly after deciding to prep for taming her, watched 4 megos gang up on her. She didn’t resurface :’(
