Part of a skeleton recovered from an ancient cemetery in the Chicama valley of northern Perú is described. The cemetery and its artifacts have been archeologically identified as those of the Mochica culture which existed between 200 A.D. and 800 A.D.
On roentgenographic and gross pathologic examination, the skeletal parts showed evidence of classic craniometaphyseal dysplasia. The skull was not recovered. The sectioned bone contained an overabundance of normal cancellous bone within the area of which there is no formation of a medullary space. These findings support Rubin's hypothesis that this dysplasia is due to failure of resorption of the secondary spongiosa.
