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.
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 due to time. The refractive index of mammoth ivory is about 1.54, and the density is about 1.70g/cm3.
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.
Fossils of species:
The place where mammoth fossils are most unearthed is near the Arctic Circle. Eskimos in Alaska use ivory fossils to make doors. There is an island in Russian territorial waters along the Arctic Ocean, which is covered with mammoth fossils.
These fossils were brought out of the mud on the shore when the ice flowed and accumulated on the island. Mammoth fossils have also been found in northeast China, Long Island, Inner Mongolia and Ningxia. Like the "keel" in Chinese medicine, it can also be used as medicine.
