UNSM preserves eight presacral vertebrae, most likely corresponding in position to the sixteenth to twenty-third presacral vertebrae, as determined through comparison to the well-known axial skeleton of Hesperornis regalis (; in birds vertebral numbering starts with the atlas, which is counted as the first presacral—see).
Marsh named Hesperornis crassipes in (originally named it Lestornis crassipes, based on an incomplete skelton with teeth and parts of the skull). Hesperornis crassipes was larger than Hesperornis regalis, had five ribs (Hesperornis regalis had four), and had slightly different looking bones in the breastbone and lower leg. Hesperornis was a prehistoric flightless bird from the late Cretaceous period. It couldn't fly like other birds do, instead it swam as the modern penguins do. A species of Cretaceous birds that are over six feet long and look similar to penguins. They were so vociferous, it was deafening being in the middle of a colony. They’re flightless, like penguins, but they were far from as cute.
Beginning in , Marsh led a series of four student expeditions to the West, securing a number of fossil bird bones, including a nearly complete skeleton of Hesperornis. (Source: Oceans of Kansas). The success of these expeditions culminated in the publication of O.C. Marsh’s; Odontornithes: A monograph on the extinct toothed birds of North. Partial reconstruction of hindlimb myology and syndesmology of Hesperornis regalis, based on fossil and extant comparative anatomical material, is provided. book summarizes the results of the.

The upper division of the foramen transmits in birds the tendon of the obturator internus muscle, a rather curious point. Of the segments of the hind-limb, the femur is remarkably short and very broad in Hesperornis and the Divers; while the tibio-tarsus is of great length in Ratitae and Waders.
The fibula is as long as the tibia in Archaeopteryx. The type specimen of a large, flightless marine bird, Hesperornis regalis, was collected by O.C. Marsh in Due to the practices of the time, and the lack of accurate maps, the type locality.
