Finding a shark tooth on the beach or while fossil hunting is an exciting experience. But how can you be sure it's authentic? Distinguishing real shark teeth from cleverly crafted fakes requires a keen eye and understanding of their characteristics. This guide will equip you with the knowledge to confidently identify genuine shark teeth.
What are the telltale signs of a real shark tooth?
Real shark teeth possess several unique features that distinguish them from imitations. These features often involve texture, color, weight, and structure.
Texture: Real shark teeth exhibit a distinct, natural texture. They are rarely perfectly smooth. You'll often notice subtle variations in surface texture, pitting, or striations (fine lines or grooves) – signs of natural wear and tear from years spent in the ocean or buried in sediment. Fake teeth often have a uniform, overly smooth, or artificial texture.
Color: While color can vary greatly depending on the age and preservation of the tooth, genuine shark teeth generally display a natural coloration. This may range from off-white or gray to various shades of brown, yellow, or even black. The color should be consistent throughout, with natural variations rather than abrupt changes. Fake teeth sometimes exhibit unnatural, vibrant, or uniform coloring.
Weight: Real shark teeth often feel surprisingly heavy for their size. This is due to the density of fossilized material. A fake tooth, particularly one made of plastic or resin, will likely feel significantly lighter.
Structure: The structure of a real shark tooth is often complex, with distinct enamel (the hard outer layer), dentin (the inner layer), and sometimes root structures still attached. These elements often display natural wear, chipping, or imperfections. Fake teeth often lack these intricate details or exhibit an unrealistic uniformity.
How do I distinguish a real shark tooth from a fake one?
Beyond the basic features, several tests can help you differentiate a real shark tooth from a fake.
The Toothpick Test:
Gently try to scratch the surface of the tooth with a toothpick. A real shark tooth's enamel will be resistant to scratching, while a fake (especially one made of plastic or resin) might show scratches easily. However, be mindful; excessive scratching can damage even a real tooth.
The Magnifying Glass Test:
Examine the tooth closely using a magnifying glass. Look for microscopic details, such as fine striations or variations in texture. Fake teeth often lack the fine detail that you would find on a real tooth.
The Acid Test (Use With Caution):
This test should only be performed on teeth you are certain are not valuable or historically significant. A small amount of dilute vinegar (acetic acid) can be applied to the tooth. Real fossilized teeth might exhibit a slight reaction, while fake ones may not react at all. Always test on an inconspicuous area and proceed with extreme caution. This is not a definitive test and may damage some real teeth.
The Weight Test:
Compare the weight of your suspected tooth to a similar-sized object made of known material (e.g., plastic or bone). A real shark tooth of similar dimensions will feel heavier.
Are there any common materials used to make fake shark teeth?
Many fake shark teeth are crafted from readily available materials such as plastic, resin, or even painted bone. These materials may mimic the general shape and color of a real shark tooth, but they lack the natural texture, weight, and microscopic detail of the genuine article.
What are some other things to consider?
- Location of discovery: Knowing where you found the tooth can be helpful. If you found it in a location known for shark fossils, it increases the probability of its authenticity.
- Overall appearance: Does the tooth look natural and consistent with known examples of shark teeth? Does it have unrealistic features or colors?
- Price: If the price seems too good to be true, it probably is. Authentic, rare, or particularly large shark teeth can be quite valuable.
By carefully examining your potential shark tooth using these techniques, you can confidently determine if your treasure is a real find from the ocean’s ancient past. Remember to always handle fossils with care to preserve them for future study and appreciation.
