Identifying Shark Teeth
Identifying shark teeth involves examining size, shape, texture, color, and root structure. Look for triangular shapes with serrations or distinctive patterns. Modern teeth are glossy, while fossils are darker and smoother, aiding in distinguishing their origin. Comparing specimens with reference guides or expert illustrations helps determine species, such as recognizing Megalodon’s broad triangles or tiger sharks’ coarse serrations; This process combines observation and knowledge to unravel the mysteries of these ancient and modern dental treasures, making every find a potential clue to a shark’s history.
3.1 Key Characteristics for Identification
Identifying shark teeth begins with examining their size, shape, and texture. Most teeth are triangular, with serrations or smooth edges, depending on the species. The root structure, either complete or fragmented, provides clues about the tooth’s origin. Color varies from glossy black in modern teeth to darker, more muted tones in fossils. Serrations, such as those found on tiger shark teeth, are distinctive, while Megalodon teeth are noted for their massive size and broad triangular shape. These characteristics, combined with reference guides, help enthusiasts accurately determine the species, whether it’s a fossilized relic or a modern dental specimen.
3.2 Distinguishing Fossilized vs. Modern Teeth
Fossilized shark teeth are typically darker in color, often black or brown, due to mineralization over time, while modern teeth are lighter, ranging from white to tan or gray. Fossilized teeth may have a matte finish and are more brittle, while modern teeth retain a glossy appearance and are harder. The roots of fossilized teeth are often worn or eroded, whereas modern teeth usually have intact roots. Serrations on modern teeth are sharper and more defined, whereas fossilized teeth may show wear. These distinctions help collectors and enthusiasts determine whether a tooth is ancient or from a contemporary shark species.
