Radiologically, the hallmark of the disorder is bilateral, symmetrical cortical thickening of the diaphyses of the long bones occuring on both the periosteal and endosteal sides of the diaphyses.
In predominantly cortical regions such as long bone diaphyses, BMD declines only minimally [68].
Harsanyi (1993) reported that the diaphyses of long bones of infants and foetuses contracted by some 10% in length after cremation, while Muller et al.

Preserved skeletal elements of 'Ayn Qasiyya 1 include a fragmentary cranial vault, including portions of the frontal, occipital, left and right parietal and temporal bones, maxillae, mandible and a partial dentition, a partial right clavicle, right and left humeri, diaphyses of the left radius and ulna, left and right femora, tibiae and fibulae.
Fazekas and Kosa (1978) and Petersohn and Kohler (1965) noted the general principle in their analysis of diaphysial shrinkage that decrease in length is inversely proportional to increase in lunar age of the fetus and Huxley (1998) devised tables based on their data for percentage shrinkage of bone diaphyses for each lunar month in utero.
