Its place is taken by two cartilage bones, the basioccipital and basisphenoid, situated along the basis cranii. In contradistinction to the Amphibia, only a single condyle connects the skull with the vertebral column: this, on close examination, is seen to be formed of three parts, derived from the basioccipital and exoccipitals Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Wiedersheim, Robert, 1848-1923; Parker, William Newton, 1857-1923.
