Asiahesperornis lived in what today is Kazakhstan and was a member of the Hesperornithes but relationships are not resolved.
It lived in what today is Kazakhstan, at its time the shores of the shallow Turgai Sea. It was a member of the Hesperornithes, flightless toothed seabirds of the Cretaceous. 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.
