How can you tell if ivory is fossilized?

From the outside and at first glance they most often look very similar, particularly from dark river deposits. The key difference for identifying fossil ivory is the “cross-hatch” pattern at the end or cross section of the specimen. Ivory, as you may know, comes from the tusks of both extinct and modern elephants.

Click here to read about large prehistoric mammals discovered in Florida. How to Identify Fossil Ivory One of the questions I often get asked is “How can you tell the difference between fossil bone and fossil ivory”. From the outside and at first glance they most often look very similar, particularly from dark river deposits. The key difference for identifying fossil ivory is the “cross-hatch” pattern at the end or cross section of the specimen. Ivory, as you may know, comes from the tusks of both extinct and modern elephants. Here is a picture of a Juvenile Mastodon lower tusk cross section. Look at the end of this piece and notice the cross-hatch pattern. That is the clear tail sign of fossil ivory. The Schreger Pattern is the name for this cross-hatch pattern in the ivory, which forms alternating light and dark spiraling bands. Each species of Proboscideans can be determined by the angle of this pattern. Mastodons and Mammoths can be predicted about 95% of the time, by the differences in this pattern. Fossil Ivory or Prehistoric Ivory in Florida, either Mastodon or Mammoth is highly mineralized and usually brittle, thus it is unusable for carving, etc. However, Mammoth Ivory from Alaska, Canada, and Siberia that has been frozen in the permafrost is very carvable and very similar in properties to modern elephant ivory.

U.S. Customs Agents use the Schreger Pattern to determine if imported ivory is legal. Unless accompanied with permits or proper documentation, modern elephant ivory is not legal to import. However, Mastodon and Mammoth Ivory is legal to posses and import. So how can they tell the difference?

Apparently, if the angle of the cross-hatch pattern is less than 90 degrees, the ivory is fossil mammoth (mammoth forms angles of 87 degrees on average). If the cross-hatch angle is more than 90 degrees, the ivory could be modern elephant (modern elephant ivory forms angles greater than 115 degrees.) On the other hand, Mastodons cross-hatch angle is 125 degrees on average. It’s a good skill to know how to identify fossil ivory from fossil bones. Even a better skill if you can look at tusk ivory and tell what type of Proboscidean or elephant it came from.

What Are the Different Shades of Ivory?

Like all colors, the color ivory comes in a variety of shades. The original hue can be tinted to become lighter or darker by using a solid gray. The color often gets darker when more black is added, and lighter when more white is added. You may see some of the different shades of ivory color below.

Arcadia White (#F3F0E0)

A color off-white is called arcadia white. This color, which is also similar to ivory white color, has the ideal balance of color and brightness, helping to provide depth without seeming too yellow or peachy.

This color can be defined as a light grayish-yellow which is closest complementary hue to this ivory tint. This color would go well with other warmer gray color options since it is a warmer color.

This specific shade is more yellow-based than ivory color, so it looks more like cream. It is a complementary color to light blue, which provides a sharp contrast.
