Use either Dunkleosteus or Carbonemys to tank damage as these dudes are only tameable when grappled onto something. They take black pearls in stacks of 50. If not Insta tamed it will be hungry for a next depending on its food stat so typically higher levels take longer between each feed. Get black pearls from mass killing trilobites, sea scorpion things (can’t spell name lol) and ammonites. You can get a decent amount from killing alpha mosas and tusos as well. Good luck!!
