The material of the study was the skull of an 8-year-old girl. In the cranioscopy, the following were identified: on the right side, the bone of the sphenoid fontanel or epipteric bone; bones of lambdoid suture - on the right side in the amount of 5, on the left side -1 bone; preinterparietal bone, ospreinterparietale.By the craniometric method, the height and width of the bones were determined. The bone of the sphenoid fontanelle or epipteric bone is located between the frontal, parietal bones, the greater wing of the sphenoid bone, and the squama of the temporal bone. The width of the epipteric bone is 16.5 mm, height 9.5 mm. The bones of the lambdoid suture in the amount of 5 on the right and the 1st on the left were located in an elongated state.The largest bone was located in the middle of the right lambdoid suture; apparently, it was formed by the union of at least two Wormian bones. Preinterparietal bone has a triangular shape, the base of the triangle facing the sagittal suture, the tip, slightly rounded - in the direction of the occipital bone. The lateral angles of the preinterparietal bone are serrated, which, in principle, clearly distinguishes it from the parietal bones. The bone was single, no sutures or grooves dividing the preinterparietal bone into parts were observed. The width of the bone is 18.5 mm, height 13.8 mm.
