Weekly Facts: The Hesperornis

Hesperornis was a large flightless bird that lived from the Late Cretaceous period to the first part of the Campanian age. The large creature had a beak full of small sharp teeth, had very small wings, and large feet that were lobed (like a grebe) rather than webbed (like a loon).

Like the mosasaurus, hesperornis' teeth sat in a longitudinal groove as opposed to individual sockets!
