Complete Guide to Shark Teeth Types
Explore our comprehensive database of shark teeth types from modern species to prehistoric fossils. Learn identification features, characteristics, and find tips for successful beachcombing and fossil hunting.
Modern Shark Teeth Types
Modern shark teeth vary by species and by position in the jaw. Compare several visible features before choosing a likely match in the app.
Great White Shark Teeth
Great White shark teeth are triangular with serrated edges, typically 1-2 inches in length. They're broad at the base and taper to a sharp point, perfect for cutting through prey.
Tiger Shark Teeth
Tiger shark teeth are distinctive with their curved shape and pronounced serrations. They're designed for both cutting and gripping, making them unique among shark teeth types.
Bull Shark Teeth
Bull shark teeth are triangular and broad, with fine serrations. Upper teeth are broader for cutting, while lower teeth are narrower and more pointed for grasping.
Prehistoric Shark Teeth Types
Fossilized shark teeth represent millions of years of evolution and are among the most popular finds for collectors. These prehistoric specimens tell the story of ancient marine ecosystems.
Megalodon Teeth
Megalodon teeth are the most sought-after fossils, ranging from 3-7 inches in length. They're triangular with fine serrations and typically dark brown or black from fossilization.
Otodus Teeth
Otodus teeth are smooth-edged and triangular, representing the ancestor of Megalodon. They're typically 2-4 inches and lack the serrations of their descendants.
Sand Tiger Shark Fossils
Fossilized Sand Tiger shark teeth are narrow and curved with smooth edges, often found in large quantities at fossil sites worldwide.
Shark Teeth Identification Features
Shark tooth identification relies on visible features such as crown shape, root structure, serrations, proportions, and wear. The app suggests a likely species you can compare with those details.
Size and Shape
Tooth size varies dramatically between species, from tiny cookie-cutter shark teeth to massive Megalodon specimens. Shape ranges from needle-like to broadly triangular.
Serration Patterns
Serrations along tooth edges vary by species and diet. Cutting teeth have fine serrations, while gripping teeth may be smooth or have coarse serrations.
Root Structure
The root system provides crucial identification clues. Some species have deep V-shaped roots, while others feature broad, flat bases with nutrient grooves.

Common questions about this feature
How many different shark teeth types exist?
Shark species can have different upper and lower teeth, and tooth shape can also vary by jaw position. Compare the crown, root, serrations, and proportions instead of relying on one feature.
What's the difference between modern and fossilized shark teeth?
Modern shark teeth are typically white or light-colored and lighter in weight. Fossilized teeth are darker (brown, black, or gray) and heavier due to mineralization over thousands of years.
Which shark teeth types are most commonly found on beaches?
The most common finds include Tiger shark, Bull shark, Lemon shark, and Sand Tiger shark teeth. Great White teeth are rarer finds, while Megalodon fossils are extremely valuable discoveries.
How can I tell if a shark tooth is authentic?
Check the crown-to-root transition, wear, color variation, serrations, surface texture, and provenance together. The app can suggest a species, but it cannot certify authenticity.
