Physical properties
Hardness: 3-5 (varies by mineral replacement), Color: Brown, tan, or grey, Luster: Dull to waxy on scales, Structure: Ganoid scales in a rhombic pattern, Matrix: Sedimentary limestone or shale.
Formation & geological history
Formed via permineralization during the Mesozoic Era (Jurassic to Cretaceous periods), approximately 100-150 million years ago, in ancient lacustrine or marine environments.
Uses & applications
Paleontological study, educational displays, and private fossil collection.
Geological facts
Lepidotes was an extinct genus of ray-finned fish known for its thick, armor-like scales called ganoid scales, which were coated with a hard enamel-like substance called ganoine.
Field identification & locations
Identified by the distinct diamond-shaped scale pattern. Commonly found in the Santana Formation of Brazil or the Solnhofen Limestone of Germany. Collectors look for scale articulation and 3D preservation.
