One of these (Fig. 3EeI), the most
abundant, can be assigned to Pan-Pleurodira because it shares
several characters with the diagnosis of this node (sensu Gaffney
et al., 2006): it has a sutural articulation of the ilium with the
costal plates, and a sutural articulation of the pubis and ischium
with the xiphiplastron; and the morphology of the ilium scar
suggests that the dorsal part of this bone is broad and robust, being
close to the midline.
