Dorsal part of the cranium is formed of two large and flat frontoparietal which are articulated together by a mid dorsal sagittal suture together and are collectively called frontoparietal. Endo-frontoparietal consists of a frontal bone (in front) and a parietal bone (behind). But now it has been proved that it is only the frontal bone, the parietals are not present in frog due to the absence of neck.
