One of our extensive collection of child skulls, this skull is estimated to be an age of 3 1/2 to 4 1/2 years. The skull of this young child shows, in perfect detail, an entire set of deciduous (juvenile) dentition in both the upper and lower jaws. It serves as an excellent educational tool and reference specimen for the evaluation of deciduous dentition and evaluation of a sub-adult skull for the purposes of age determination. Furthermore, osteologists can appreciate the "open" nature of the sutures, including the basilar (spheno-occipital synchondrosis) suture, a sign of skeletal immaturity.
