Mammoths are mammoths. They lived in the Ice Age. Paleontologists found a well-preserved mammoth corpse in the frozen ice of Siberia, so there was a well-preserved mammoth ivory. Mammoth ivory is the front tooth of mammoth, commonly known as ancient tooth, also known as the tooth of ten thousand years. The original size of mammoth ivory is larger than that of modern ivory, and most of it has been calcified or petrified because of its age. Only a small part of mammoth ivory, an ice material preserved in the frozen soil of the Arctic Circle, can be used for carving.

Only about 15% of the discovered mammoth ivory can be used for carving, and other calcified or petrified parts cannot be used for carving. China sells mammoth ivory and its carved products, the main source of which is excavated in the frozen soil of Siberia. Due to the limited resources, with the continuous exploitation and excavation, mammoth ivory will be less and less.

There is an essential difference between ivory and mammoth ivory, that is, mammoth ivory is a fossil, while ivory is alive. The sale of mammoth ivory in China requires relevant certificates. Sales are legal only if there are relevant certificates.
