Elephant tusk

African Elephant

Description

The source of true ivory. Long, curved elephant tusks are rootless incisors that are not covered with enamel. The size and structure of a tusks depends on the animal, its age and its living conditions. Tusks as long as 6-8 feet have been obtained from African elephants. The Indian elephants produce tusks about 4-5 feet long. The tusks are primarily composed of dentin, a hard calcareous material; a new layer of dentin is added each season. This produces a layered ring structure that can be seen in fresh ivory. Deteriorated ivory tends to flake and peel along these lines.
