"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

"Ichthyornis victor and I. dispar, ...were small forms of about the size of a Partridge, with the habits and appearance, it is presumed, of Terns or Gulls. The head was extremely large in proportion to the remainder of the skeleton; the beak was long and pointed, with entirely separate rami to the mandible; the sharp teeth, fixed regularly in distinct sockets, were inclined backwards, and occupied the whole of the lower and at least the posterior half of the upper jaw; the keel of the sternum was large and broad; the dorsal and cervico-dorsal vertebrae were biconcave. the quadrate articulated to the skull by one knob,... the metatarsus was short and the whole foot small; a furcula was probably present; the wings were well developed, indicating great powers of flight; while the tail was comparatively short, and ended in a pygostyle."

Lancelet fish (Branchiostoma) is sometimes called amphioxus, the type of the class Leptocardii, is a little creature, half and inch to four inches long. A lancelet may be regarded as a vertebrate reduced to its lowest terms. Instead of a jointed backbone, it has a cartilaginous notochord, running from the head to the tail. A nervous cord lies above it, enclosed in a membranous sheath. No skull is present and the nerve cord does not swell into a brain There are no eyes and no scles. The mouth is a vertical slit, without jaws. In this diagram we see the California lancelet twice the natural size, showing (g) gills, (l) liver, (m) mouth, (n) nerve cord, (nc) notochord.
