Restoration of Hesperornis regalis
“Hesperornis regalis, (a fossilized restoration) which stood about three feet high, had blunt teeth in the grooves of both maxilla and mandible, the number being thirty or more below, but considerably less above, where they did not reach to the exterior extremity. The bill was long and pointed, the rami of the lower jaw being entirely separate; the head was rather small, the neck long, and the quadrate bone articulated with the skull by one knob only. The sternum was long, broad, and flat, without keel; the furcula was decidedly reduced, the metatarsus, being little more than a humerus; the tail was fairly long and broad, but had no pygostyle.” A. H. Evans, 1900
