I saw one of these fellas in a nearby river surrounded by spinos, fortunately I was able to reach it, but the thing is I am a total noob so I tried to knock it out and feed it some fish but right after I did so my dodo murdered it without any hesitation, the poor thing squeaked as it was killed brutally, moral of the story, never underestimate your dodo, especially if you’re around a otter.
Just push this cute lil creature in front of a giga and it'll have an existential crisis. Realising the path of destruction it left in its wake and deteriorate in front of the otters blue sparkly marble eyes
It is tamed in the same way as the Hesperornis, where you have to carry a dead fish to it. Larger fish, and those caught by Ichthyornis, apparently work better. Piranha are better than coelacanths for taming, and salmon are better than piranha.
