About This Fossil
Knightia lived in huge shoals in large freshwater lakes during the Eocene, around 50 million years ago.
They come from one of the most famous fossil sites on Earth, the Green River Formation in Wyoming, Utah, Colorado.
These are early ray-finned fish, herring-like, and some of the most recognisable fossils you can find.
Formation & Preservation
Knightia fossils form in low oxygen environments as the fish sat at the bottom of the river, protected from predators. Lime sediment deposited on top of the bodies preserve and compress them in limestone as the organic material is replaced by carbon and minerals.
What Makes This Specimen Special
Authenticity & Sourcing
Real vs Replica
- This is a genuine fossil. Authenticity guaranteed in writing.
- You will receive the exact specimen you select.
Ethical Sourcing
- Sourced from established, long-standing suppliers and known commercial sites — never protected, scientifically significant, or restricted localities.
- ✓We will not knowingly handle fossils removed in breach of any country's heritage or export laws.
Origin & Natural Variation
Stated origin (Wyoming, Utah, Colorado (USA)) and formation (Green River Formation (USA)) reflect the best information from our supplier and accepted geological literature. Where exact locality cannot be independently verified, we describe the formation rather than a single quarry.
Fossils are natural objects. Expect minor variation in colour, matrix, mineralisation, and surface detail. Any significant repair, restoration, or composite preparation is disclosed in the description — we never present restored areas as original without saying so.
