An analysis of the ontogenesis of the chondrocranium gives the following homologies in the skull of Lacerta and Chelydra: (see article). It is shown that the extracranial position of the cavum epiptericum in Lacerta corresponds to the stage of maximal development of the chondrocranium in Chelydra. But further development brings about a dermal sidewall in the orbitotemporal region, b,ilt up by descending parietal flanges which incorporate the epipterygoid. This not only allows the pila antotica to degenerate but also incorporates the cavum in the cranial cavity.
（见文章）。结果表明，蜥蜴中翼窝的颅外位置对应于鳄龟软骨颅最大发育阶段。但进一步发育会在眶颞区域形成一个由下降的顶骨翼突构成的真皮侧壁，该侧壁并入了翼蝶骨。这不仅使前耳柱骨退化，还将翼窝纳入颅腔。
