Abstract: This especially small human skull (known as T1) was from a Chinese male with a height of 168 cm and aged about 40 years. Upon measuring and observing various skull features, the following observations are made. The skull is especially small in overall size; the frontal region is particularly small and narrow but the surface area of the skull is relatively large. The maxilla and mandible jut forward prominently. As expected with the small skull size, standard skull measurements, including length, width, height and arc, chord and perimeter are less than the minimum values found in other skeletal reports. Cranial volume is also less, and is assessed at 602 ml, which is less than half of the reported minimum volume of 1340 ml for most humans.

Key words: Skull observation; Skull measurement
