FIGURE 48. The posterodorsal crest on the supraoccipital in Sphenodon (large apparently unregisted specimen in the Zoology collection of Ernst Moritz Arndt University, Greifswald) viewed in anterolateral aspect (48.1) and left lateral aspect (48.2). According to Al-Hassawi (2004, 2007) the supraoccipital crest is where the m. Axis-Supraoccipital attaches. The crest projects posterodorsally approximately 4 mm.
