Claim: The one who had a unresolved relationship and was a member of the Hesperornithes was Asiahesperornis lived in what today is Kazakhstan (a transcontinental country)
Evidence: Its exact relationships are not completely resolved, but it probably belongs into the Hesperornithidae just like Hesperornis, well known from the Western Interior Seaway that covered most of the US Midwest in the Mesozoic. It was a member of the Hesperornithes, flightless toothed seabirds of the Cretaceous. It lived in what today is Kazakhstan, at its time the shores of the shallow Turgai Sea. Kazakhstan, officially the Republic of Kazakhstan, is a transcontinental country mainly located in Central Asia with a smaller portion west of the Ural River in Eastern Europe.
