Finding a shark tooth, whether on a beach, in a fossil dig, or at a market, can be an exciting experience. But how do you know if that pearly white treasure is the genuine article or a cleverly crafted imitation? This guide will equip you with the knowledge to distinguish real shark teeth from fakes, helping you confidently identify your find.
What are the Key Differences Between Real and Fake Shark Teeth?
The key lies in understanding the characteristics of natural shark teeth. Fakes often miss crucial details, offering shortcuts that betray their artificial origins. Let's explore those critical differences:
1. Weight and Feel:
Real shark teeth possess a distinct weight and feel. Genuine teeth have a solid, weighty presence, unlike their lighter, sometimes plasticky counterparts. Hold the tooth and compare its feel to similar-sized objects. Does it feel surprisingly heavy for its size? That's a positive sign.
2. Color and Texture:
Natural shark teeth exhibit subtle variations in color and texture. They rarely possess a uniformly perfect, bright white hue. Instead, you'll often find variations in color, with shades of gray, yellow, brown, or even black, often concentrated at the root or tip. The surface will also display a natural, uneven texture, rarely flawlessly smooth. Fake teeth tend to have a more uniform and artificial appearance.
3. Enamel and Root:
Examine the tooth’s enamel. Real shark teeth have a smooth, glossy enamel coating, which is much harder than the underlying dentin. The root, which anchors the tooth to the jaw, will be porous and often retains fossilized remnants of the jawbone or surrounding sediment. Fake teeth often lack these natural imperfections in the enamel and root structure.
4. Tooth Shape and Structure:
Each shark species possesses uniquely shaped teeth. Research the common shark species in the area where you found the tooth (or where you purchased it). Compare the tooth's shape, serrations (if any), and overall structure to images and descriptions of known shark teeth. Inconsistencies could signal a fake.
How to Identify Specific Types of Shark Teeth:
The identification process can be further refined by considering the specific type of shark. The shape, size, and serrations significantly vary between species. For instance:
-
Great White Shark Teeth: These are triangular, robust, and have serrated edges.
-
Tiger Shark Teeth: These are also triangular but generally show less serration and a more curved edge.
-
Mako Shark Teeth: These are slender, triangular teeth with fine serrations.
-
Hammerhead Shark Teeth: These are narrow, pointed teeth with less pronounced serrations.
How Can I Tell if a Shark Tooth is Fossilized?
Fossilized shark teeth, found in ancient sediments, exhibit distinct characteristics:
-
Coloration: Fossilized teeth often possess darker shades due to mineralization.
-
Weight: They can be quite heavy due to the minerals that have replaced the original tooth material.
-
Texture: The surface might appear rough or pitted due to the fossilization process.
What if I Still Have Doubts?
If you remain uncertain about the authenticity of a shark tooth, consider seeking the opinion of a paleontologist, geologist, or experienced fossil collector. They possess the expertise to accurately identify the tooth and determine its origin.
By carefully examining the tooth's weight, color, texture, shape, and structure, and comparing it to known species, you'll significantly enhance your ability to discern a genuine shark tooth from a replica. Happy hunting!
