How to Tell If a Shark Tooth Is Real

Ever stumbled upon a shark tooth at a beach or a souvenir shop and wondered if it’s the real deal? You’re not alone. With the market flooded with replicas, distinguishing a genuine shark tooth from a fake can be tricky but incredibly rewarding.

In this guide, I’ll share some simple yet effective tips to help you identify authentic shark teeth. Whether you’re a beachcomber, a collector, or just curious, you’ll find these insights invaluable for making sure your find is the real McCoy.

Understanding Shark Teeth

Shark teeth possess unique traits that make them distinguishable from other fossils and replicas. Here’s what to look for when identifying and categorizing them.

Characteristics of Shark Teeth

Shark teeth exhibit a triangular shape with sharp edges, which are key indicators of their carnivorous nature. Authentic shark teeth often show a distinct central axis and finer serrations along the edges. The enamel on real shark teeth is smooth, shiny, and robust due to their marine environment. Natural wear or darkening appears on older shark teeth because of mineral absorption over time.

Types of Shark Teeth

Understanding the different types of shark teeth aids in identification. Tiger shark teeth, for example, have a distinctive notch and curved shape. Great white shark teeth are large, triangular, and serrated. Fossilized megalodon teeth are massive, reaching lengths of over 7 inches. Smaller species, like the sand tiger shark, possess long, slender teeth with smooth edges. Each species contributes to the diverse range of shark teeth found in various archaeological sites and seabeds.

Identifying Real vs Fake Shark Teeth

Determining if a shark tooth is real involves several methods, both physical and scientific. I’ll explain key techniques to help you distinguish authentic shark teeth from imitations.

Physical Examination Techniques

Feel the Edges: Examine the tooth’s edges; genuine shark teeth have sharp, serrated edges. Run your finger along the edges to detect this feature. Fake teeth often have blunt or smooth edges.

Check the Enamel: Authentic shark teeth have a shiny, enamel-coated surface. This sheen comes from natural preservation. Replicas typically lack this natural shine and may appear dull or overly glossy.

Inspect for Wear: Genuine teeth often show signs of wear due to their time in the ocean. Look for abrasions or slight chipping. Fake teeth usually lack these signs or exhibit uniform wear, indicating artificial aging.

Compare Sizes and Shapes: Real shark teeth exhibit variations in size and shape due to different species and growth stages. Check for consistency; replicas sometimes display uniformity, a sign of mass production.

Scientific Methods for Verification

X-ray Imaging: Use X-ray imaging to inspect the internal structure. Natural shark teeth have distinct density patterns. Fake teeth often fail to replicate these patterns accurately.

Chemical Analysis: Perform a chemical analysis to identify composition. Authentic teeth contain specific mineral compositions like calcium phosphate. Imitations might use different materials.

Fluorescence Test: Conduct a fluorescence test under UV light. Real teeth can exhibit specific fluorescence due to their mineral content. Replicas often lack this characteristic or fluoresce differently.

Histological Study: Examine the microscopic structure by slicing a thin section. Genuine shark teeth have a unique histological pattern. Fake teeth don’t replicate this cellular structure accurately.

These techniques, both physical and scientific, provide comprehensive ways to verify the authenticity of shark teeth.

Sources to Purchase Authentic Shark Teeth

Purchasing authentic shark teeth involves examining reputable sources and avenues. Here are reliable methods to find genuine shark teeth.

Online Retailers and Auctions

Various online platforms offer authentic shark teeth. Websites like FossilEra, eBay, and Etsy list both modern and fossilized shark teeth. Sellers on these platforms often provide detailed descriptions and provenance information. When buying, I recommend checking seller reviews, asking for certifications, and verifying return policies. Auctions hosted by established auction houses can also be a good source, as they often have experts verify the authenticity of items before listing.

Beachcombing and Diving Spots

Finding shark teeth through beachcombing and diving adds an element of adventure. Beaches in regions like Florida, South Carolina, and Maryland are renowned for their shark teeth discoveries. Visiting these spots after storms or rough tides increases the likelihood of finding teeth. Diving spots such as Venice Beach in Florida are another excellent resource. If conditions permit, I suggest joining organized diving trips led by local experts who can guide you to the best locations for finding shark teeth.

Maintenance and Care for Shark Teeth

Preserving the condition of shark teeth enhances their appearance and value. These tips cover cleaning and showcasing them effectively.

Cleaning and Preservation Tips

Clean shark teeth with warm water and a soft brush to remove dirt. Avoid abrasive materials since they can scratch the surface. For stubborn residues use a mild, diluted vinegar solution. Dry them thoroughly to prevent mold formation. Store teeth in a cool, dry place away from direct sunlight to maintain their color.

Displaying Shark Teeth

Use clear display cases to protect teeth from dust and damage. Arrange them on black velvet backgrounds for contrast. Label each tooth with species name, age, and location of discovery for educational value. Rotate the display periodically to minimize potential exposure to light which can fade colors over time.


Identifying real shark teeth can be a rewarding challenge that deepens our appreciation for these fascinating marine creatures. With the right techniques and sources, anyone can confidently distinguish genuine shark teeth from imitations. Proper care and creative display methods ensure these treasures remain in great condition for years to come. Whether you’re purchasing from reputable sellers or discovering them on your own adventures, the thrill of owning a piece of natural history is unmatched. Happy hunting!
