I would like to correct anatomical error in the description of walrus tusk written in the book on identification of various osteological materials. The author calls the inner marbled ( oatmeal-like, granulated etc.) part of the tusk a " pulp". It is not a pulp. Pulp of any tooth is a soft living tissue located in the middle of the tooth and composed of arteries, veins, nerves and some supporting soft tissue. It is locates in the so-called " pulp cavity" that originates at the basis of the root and disappears completely well before the tip of the tooth. It provides nutrients to the cells lining the dentine that are responsible for tooth growth. When we have root canal procedure, the pulp is what is removed by our endodontists:-((( The jello-like consistency of the pulp makes it absolutely unsuitable for any practical use in the process of carving.
Walrus tusk is a modified canine tooth. Its outer layer is enamel, that is worn off at a very young age. Underneath is cementum, also thin and flaky material that is removed by the carver. The rest of the tusk consists of dentine and this part is used for carving purposes. The outer layer of the dentine is homogeneous (primary dentine) and the inner part ( secondary dentine or osteodentine) is exactly the one that is erroneously called " pulp" in the book. You can look it in the CITES book https://www.cites.org/sites/default/...vory-guide.pdf and in the U.S. Fish and Wildlife Services book https://www.fws.gov/lab/ivory_natural.php Also, a pic of the cut across the tusk:C- cementum, PD- primary dentine; SD - secondary dentine. Right in the center we can see a dark irregular structure, the final remnant of the pulp. Thus, when we discuss walrus ivory, let's use correct anatomical terminology. |

Thank you very much for the valuable addition taken from the CITES website.
In Russian (and the book is written in Russian for Russian-speaking specialists), the inner (oatmeal-like, granulated etc.) at the same time, the hard part of the walrus fang is called "pulpa". If I decide to make an English version of my book on the definition of osteological materials, I will definitely describe the structure of the walrus fang, as is customary in the English scientific literature ![]() |

For your benefit I am attaching a slide from a Russian source with Latin names for different tooth components ( for the benefit of other Forumites). If you do not trust it, you can consult any Russian book on anatomy or dentistry or Google it in Russian. Just admit your goof, say thank you and that's it. The more you try to dig yourself out , the deeper you get. |

![]() There are many specific linguistic circulation in the Russian language that you are not familiar with due to the specifics of your profession. This is normal. You can’t know everything. But this is not scary. We are all learning. I did not say anything about the structure of the tooth. Therefore, you put a picture in the subject in vain ![]() So you don’t have to try to seem smarter than it really is ![]() I propose to continue the discussion of the Khyber knife of Norman. Of course, if someone can say something new. P.S. I must add that the manuscript of the book has a positive response from a leading specialist in Russia, who specializes in tusks of elephants and mammoths, as well as walrus fangs, an expert from the Ministry of Culture of the Russian Federation ![]() But, probably, you know more than this respected specialist ![]() Last edited by mahratt; 30th September 2019 at 10:59 PM. |

"Ethnographics" are usually not brutes, but stupidity among them is of the same incidence as in general population or collectors of regulation weapons. They are usually more arrogant, because there are no regulation standards, and they are free to make statements on the basis of their opinions, not on officially recorded facts. Well, as any negative trait, it can have some good in it: replace arrogance with perseverance:-) |
