The fragmentary and incomplete nature of the 41BX6 cranium restricts the number of accurate metric observations which may be taken for descriptive
purposes. Obtainable measurements and indices are provided in Table B-1. Measurement values followed by an asterisk indicate the value is
estimated.

The metric observations of the 41BX6 cranium are descriptive of an average individual. The cranial index indicates this individual as being
orthocranic, or having an average head height. The breadth-height index and the fronto-parietal index suggest the head shape may be slightly higher
and broader than average. Overall, the skull shape is characterized by its lack of distinctive morphology.

Age at Death

Age at death of the individual represented by the 41BX6 cranium is estimated from the degree of closure of the neurocranial sutures. These sutures
appear to have begun initial fusion endocranially, yet remained distinct on the exterior surface of the skull. Subsequently, it is noted the fragmentation
pattern of the skull occurred primarily along the suture lines. This pattern would not have been expected if the neurocranial sutures had been
completely fused prior to death.

The degree of suture closure indicates an estimated age of 17 to 23 years. This age estimate is supported by the morphology of the spheno-occipital
synchondrosis which suggests having not been completely fused by the time of
