A beautifully preserved fossil stingray dermal denticle, measuring approximately 1.2" overall and displaying remarkably crisp anatomical detail. 
 
The raised denticle features a pronounced central ridge bordered by fine, tooth-like serrations along both edges. Its dark blue-gray coloration contrasts dramatically against the pale fossilized tissue surrounding it, making the tiny structure surprisingly striking despite the specimen’s size.
 
Dermal denticles are hardened structures that formed part of a ray’s protective skin covering. This example remains associated with a portion of the original fossilized tissue rather than occurring as an isolated denticle, providing additional anatomical context and making it an especially interesting little marine fossil.
