An ivory-like, carvable material obtained from the horny protuberance at the base of the large upper bill on the helmeted hornbill bird (Rhinoplax vigil). The hornbill bird is native to southern Asia, Indonesia and Africa. The protuberance, called the casque, can be up to 15 x 10 x 5 inches (6 x 4 x 2 cm) in size. It is usually a creamy white to pale orange in color. Hornbill ivory is grainless and softer than elephant ivory (Untracht 1985).
