Knightia Fossil Fish – Beautifully Preserved Specimen – Green River Formation – Wyoming, USA Beautiful fossil fish of the extinct genus Knightia, a freshwater clupeomorph fish from the famous Green River Formation (Wyoming, USA). This formation is one of the most renowned fossil deposits in the world and dates back to the Eocene epoch, approximately 50 million years ago. Knightia is among the most iconic species from this locality and represents a true classic for fossil collectors. The specimen is preserved on a fine light limestone matrix, which creates an excellent natural contrast with the fossilized bones. The fish is well articulated and clearly visible, with the vertebral column, ribs, skull, and fin rays sharply defined. The dorsal and caudal fins are particularly well preserved, and the body shape is nicely displayed, giving the fossil strong visual appeal. The fossil has been carefully prepared to highlight the anatomical details while maintaining the natural appearance of the specimen. A very attractive and collectible fossil from one of the world’s most famous fossil sites, ideal both for collectors and as a decorative natural history piece.
