You need spinosaurus egg kibble to tame these?!! Why!!? It's so much easier to just feed it regular raw meat! Honestly I wouldn't even waste time going through all that, you'd be better off feeding it raw meat that way or spend more time taming a basilosaurus with Therizino kibble! (However I personally don't recommend taming these anyway, they're really bad, unless you stack loads of health on it to tame a giant squid).
