   • 1925, Samuel Wendell Williston, "Chapter 1" in The Osteology of the Reptiles

     Primitively the exoccipitals took but little part in the formation of the occipital condyle, but in many later reptiles they form a large part, as in the Chelonia (Fig. 31 b), or even the whole, as in the Amphisbaenia (Fig. 56 b); or, by the recession of the basioccipital, the double condyles of the Cynodontia and mammals.
