Knightia Fossil Fish Plate – Authentic Green River Specimen – 90%+ Whole – Eocene Era

Knightia Fish Fossil Plate – Authentic Eocene Fossil from the Green River Formation This listing is for ONE randomly selected Knightia Fish Plate Fossil, guaranteed to be 90–100% whole. These are 100% authentic fossil specimens from the world-famous Green River Formation in Wyoming, dating back to the Eocene Epoch—approximately 48 million years ago. Each Knightia fossil has been lightly cleaned to enhance visibility but contains no added artistic restoration—what you see is purely natural. Knightia eocaena was a small freshwater fish that lived in large schools, and these mass mortality fossils are often attributed to sudden environmental changes that occurred in ancient lake systems. Some fossils may have minor edge damage or imperfections, but each specimen is guaranteed to retain at least 90% of the full fish fossil. Available pieces may be rectangular, oval, or irregular in shape, and will be pulled randomly from a selection of similarly graded stock. 🔍 Product Features: Species:
