I may do a Quetzalcoatlus. My deinonychus oc's do have some sharptooth flyers in their herd so it could be they have some of these. the only thing is the members of the herd know 3 languages, sharptooth, flatooth, and a whistle language that only they know that was made initially by Blue-eye's great grandfather, with some input with Zal, so they could have a way to talk to each other over long distances, and there are real whistle languages on the earth today, but they're dying languages.
