Finding a shark tooth is an exciting experience, especially for fossil enthusiasts and beachcombers. But how do you know if that pearly white find is the genuine article or just a cleverly disguised imposter? This guide will equip you with the knowledge to distinguish real shark teeth from cleverly crafted fakes. We'll cover everything from visual inspection to advanced techniques, answering many common questions along the way.
What are the Characteristics of a Real Shark Tooth?
Authentic shark teeth possess several key characteristics that set them apart from imitations. Understanding these traits is crucial for accurate identification.
- Weight and Feel: Real shark teeth have a noticeable weight and density. They feel substantial in your hand, unlike lightweight plastic or resin replicas. Pick up a few known genuine specimens (if you have access) to get a feel for the weight-to-size ratio.
- Color and Texture: While color can vary greatly depending on the age, preservation, and species of shark, genuine teeth often exhibit a natural, slightly uneven coloration. They might show subtle variations in shade and may have minor imperfections or discoloration. Artificial teeth often have a uniform, almost too-perfect coloration. The texture should be slightly rough, not perfectly smooth.
- Enamel: Examine the surface carefully. Real shark teeth possess a layer of enamel, which is a hard, protective coating. This enamel is typically glossy, albeit sometimes worn or slightly pitted with age. Fake teeth often lack this natural gloss and feel smoother to the touch.
- Root Structure: Real shark teeth often retain at least part of their root structure. This root is typically more porous and less glossy than the enamel of the crown. Look for signs of wear and tear on the root, which are common in naturally occurring specimens.
- Natural Imperfections: Real shark teeth are rarely perfect. They might have small chips, cracks, or minor wear consistent with their natural history. Perfectly flawless teeth should raise a red flag.
How Can I Tell if a Shark Tooth is Fossilized?
Many shark teeth found are fossilized, meaning they've undergone a natural process of mineralization over time. Here's how to identify fossilized teeth:
- Weight: Fossilized teeth are often heavier than their modern counterparts due to the replacement of organic material with minerals like quartz or calcite.
- Color: Fossilized teeth can exhibit a range of colors depending on the minerals present during fossilization. Common colors include gray, brown, black, and even reddish hues.
- Texture: The surface texture can be altered during fossilization, sometimes appearing more porous or rough than a modern tooth.
What Materials are Fake Shark Teeth Made Of?
Understanding the materials used in creating fake shark teeth can help you spot them. Common materials include:
- Plastic: Often lightweight and lacking the weight and texture of a real tooth.
- Resin: Can be more convincingly crafted but often lacks the fine details and natural imperfections of a genuine specimen.
- Bone: While bone is a natural material, it’s crucial to distinguish between genuine fossilized shark teeth and other animal bones that might be misidentified.
Are There Any Tests I Can Perform?
While simple visual inspection is often sufficient, there are some additional tests that can help confirm authenticity:
- Hardness Test (with Caution): Real shark teeth are extremely hard. While you shouldn't aggressively scratch them, trying to scratch the surface with a metal object (like a carefully used knife) might help distinguish between a real tooth and a softer material like plastic. Always use extreme caution and avoid damaging the specimen.
What are the Common Types of Fake Shark Teeth?
Fake shark teeth often imitate the popular and highly sought-after varieties like Megalodon teeth. Be especially vigilant when examining teeth from this species, as they are a prime target for forgery.
How Much Does a Real Shark Tooth Cost?
The cost of a real shark tooth varies widely depending on species, size, condition, and provenance. While some common teeth might be relatively inexpensive, rare or exceptionally preserved specimens can command substantial prices. If the price seems unusually low for a supposedly rare tooth, it could be a red flag.
By carefully considering the weight, texture, color, and overall characteristics, you can significantly improve your ability to discern real shark teeth from their artificial counterparts. Remember to proceed with caution, handle specimens carefully, and prioritize learning and responsible collecting practices.
