The Bones

The diagram, displayed below, indicates which parts of the skeleton survived their 3,700 years underground. Those in bright purple are still a part of the collection today normally housed at Caithness Horizons museum in Thurso. The right femur, displayed in dark purple, was destroyed during the original carbon dating programme in the 1990’s.

The human bones were examined by Mary Harman (her full report can be found on the Highland HER record for the site found here). The bones were considered to be in a relatively well preserved state and no evidence of injury or disease was identified.

The Skull

The skull had survived in a very good condition, although the mandible and most of the occipital bone were missing. The cranium was reported as being very short and broad, although there was no sign of distortion. Harman noted that the individual had an exceptionally high cephalic/cranial index. My own measurements suggest a cepahlic index of 89.6, classified as hyperbrachycephalic bordering on ultrabrachycephalic. The skull has been examined recently (December 2015) by a burial archaeologist who has retaken these measurements (awaiting report).

The skull of this individual is particularly unique.

 

The Teeth

Harman reported that of the twenty-six teeth found, none of them had any caries, there were no abscesses in the upper jaw and there was no evidence of any periodontal disease. There were slight traces of hypoplasia near to the base of the upper first molar crown which suggested that there had been a slight disruption in the diet or health of the individual when the tooth was developing, at an age of about two years.

Most of the skeleton was recovered, although a substantial amount of the upper to mid left side of the skeleton was missing. The reasons for this are not yet known. It was likely this individual was buried lying on their side with their knees drawn up tightly under their chin. They may have been tied in this position for burial. This tradition was common amongst Bronze Age short cist burials.

Height

The left tibia measured 362mm in length and the left ulna measured 265mm in length. Using the formula of Trotter and Gleser (Brothwell, 1981, 101), Harman calculated that the height of the individual would have been 5’ 5 ½” (1.67m).

Age

Based on the evidence that all epiphyses had fused by the time of death, but the first sacral vertebrae of the sacrum had not completely joined to the rest, Harman suggested that this was the remains of a young adult. As the wear on the teeth was limited, Harman suggested that this was an individual aged between 18 and 22 years old.

Gender

Although the pelvis was too incomplete to be used for determining sex, Harman noted several other features that indicated that the gender of the individual was female. The skull had no brow ridges, the first sacral vertebra had female characteristics and the small and light size and physique of the vertebrae and limbs suggested that the remains were of a woman.
