“…Hypervitaminosis A, or vitamin A toxicity, reduces bone formation and enhances its resorption (Binkley and Kreuger, 2000). The condition has been associated with a proliferation of coarse periosteal bone on the skull and long bones and, in non-adults, delayed ossification (Naz and Edwards, 1952;Woodard et al, 1961;Walker et al, 1982;Aufderheide and Rodríguez-Martín, 1998). In the case of the Moyoro 165, bone formation appears to be limited to the mandible and is distinct in its lamellated appearance.…”
