An Enlarged Parietal Foramen in the Late Archaic Xujiayao 11 Neurocranium from Northern China, and Rare Anomalies among Pleistocene Homo (original) (raw)
Figure 3
The right parietal perforation of Xujiayao 11.
Exocranial (A) and endocranial (B) details of the opening. The bone is oriented with the opening approximately horizontal, such that anterior is above-left in the exocranial view and above-right in the endocranial view. The rounded and beveled edge is evident in the external table (C). The vascular groove is evident on the inner table (D). The arrows delimit the preserved right rounded margins of the hole, to distinguish it from the left postmortem breakage of the margins.
