Confused on taming

I was trying to tame a Basilosaurus for myself but because he is one of those dinosaurs that you can't tame by making them unconscious there was only that text on him saying „Hack Taming Speed“ so I am confused how I can tame those kinds of dinosaurs. Any help or tips? I also tried to buy that hack first for 5 keys, then for 20 keys. Then it would have cost me 80 keys but it didn't help at all.
