4 INCH SHARK TOOTH

THIS TOOTH IS A  4" LONG MEGLADON SHARK TOOTH FROM OFF THE COAST OF NORTH CAROLINA

THIS TOOTH IS 4" LONG FROM TIP TO TIP AND 3.5" AT THE ROOT

How a Tooth Becomes A Fossil

A tooth become a fossil when it is buried in sediment (or other material) soon after being lost from a shark's mouth. The sediment precludes oxygen and harmful bacteria from reaching the tooth and destroying it. The general fossilization process varies greatly depending on the exact situation. In general it takes approximately 10,000 years for a tooth to become a true fossil.

Why Fossil Teeth Are Different Colors

The color of a tooth is determined solely by the color of sediment in which it is buried while fossilizing. The tooth absorbs minerals from the surrounding sediment. As the minerals replace the natural structure of the tooth, the tooth becomes the same general color as the sediment. Therefore, color is not an effective indicator of the age of a tooth. The most common color for shark teeth is a black root with a grayish crown. Different colors are more uncommon and significantly increase the value of a tooth.

History of the Carcharocles megalodon Shark

I specialize in teeth from the Carcharocles megalodon shark which thrived during the above time period. This shark was the largest shark to ever swim the ocean. Reaching an overall maximum length of approximately 60 feet, this shark was three times the size of the modern Great White (Carcharodon carcharias) shark.

Carcharocles megalodon Teeth and What Makes Them So Valuable

The teeth from the megalodon shark are truly massive in both length and width. The largest teeth are as large as a man's hand and can weigh well over a pound. The largest complete megalodon tooth ever found measures just over 7" in slant height (measure of the longest side from tip of tooth to the top of the root). Teeth this size, however, are extremely rare. There are only a few teeth in the world that measure over 7" legitimately (however there have been lots of "stretched fakes" so be careful what you buy!!). Smaller teeth are much more common with the average size being about 3 1/2" - 4 1/2" in slant height. Teeth over 5" are uncommon and over 6" are very rare, so the value of teeth this size is significantly greater than the smaller ones.

Another factor that greatly increases the value of a tooth is the degree of preservation. The vast majority of teeth that have become fossils have been destroyed by natural processes (erosion, chemical processes, etc.). Most megalodon teeth found have undergone quite a bit of destruction, with chunks of the tooth broken off, the enamel eaten through, or significant erosion wearing the natural features of the tooth. Occasionally, one comes across a perfectly preserved tooth still bearing its original features and sheen. While uncommon, teeth like this are found and are of significant value.
