Walrus ivory

Walrus tusk ivory comes from two modified upper canines. It is also known as morse. The tusks of a Pacific walrus may attain a length of one meter. Walrus teeth are also commercially carved and traded. The average walrus tooth has a rounded, irregular peg shape and is approximately 5 cm in length.

The tip of a walrus tusk has an enamel coating which is worn away during the animal's youth. Fine longitudinal cracks, which appear as radial cracks in cross-section, originate in the cementum and penetrate the dentine. These cracks can be seen throughout the length of the tusk. Whole cross-sections of walrus tusks are generally oval with widely spaced indentations. The dentine is composed of two types: primary dentine and secondary dentine (often called osteodentine). Primary dentine has a classical ivory appearance. Secondary dentine looks marble or oatmeal-like.

Carving

Walrus ivory carving and engraving has been an important folk art for people of the Arctic since prehistoric times, among them the Inuit, Inupiaq and Yupik of Greenland and North America and the Chukchi and Koryak of Russia. The Chukchi and Bering Sea Yupik in particular continue to produce ivory. The folk art of walrus ivory carving has been popular in European Russia since the Middle Ages, with notable schools of walrus ivory carving in Kholmogory and Tobolsk. During Soviet times, several walrus carving collectives were established in villages in Chukotka, notably Uelen. International trade is, however, somewhat restricted by the Convention on the International Trade of Endangered Species (CITES).

Morse (crater)

Morse is a lunar impact crater that is located on the far side of the Moon and cannot be seen directly from the Earth. It lies about one crater diameter to the southwest of the larger Fitzgerald. To the west-northwest of Morse is Dante.

This is a relatively well-defined crater with features that have not been markedly eroded by subsequent impacts. There is a small crater along the southeastern rim, however, and the southern rim is somewhat disrupted. The rim edge is uneven in places and there are terrace features along the inner walls to the northeast and west. The interior floor, while generally level, has a number of low irregularities forming small hills.

The crater lies at the northeast margin of the Freundlich-Sharonov Basin.

Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Morse.
