Dinosaurs among the reptiles of the past gave prophecy of the modifica- tions which characterize the pelvic girdles of birds. For example, the girdle of the fossil reptile Stegosaurns (Fig. 540) shows a spreading fan-shaped ilium, a long ischium extending posteriorly without a symphysis, and a back- ward-projecting pubis on either side that runs parallel to the ischium instead.
