Os postfrontale
The Os postfrontale , also called postfrontale for short ( Latin : post = after, frons = forehead), is a small, paired cover bone of the cranial roof of the tetrapodomorpha ( land vertebrate - crown group + closest fossil relatives). It is involved in the posterior upper (caudodorsal) edge of the eye socket and thus belongs to the circumorbital series .
The post-frontal occurs in fossil "primitive" land vertebrates and in reptiles . With regard to the (recent) animals living today, it is only present in the scale creeps ( lizards and snakes ) and in the bridge lizard .
