Huge 5.3" Knightia - 18 Inch Layer
This is a huge example of the Eocene aged fossil fish Knightia eoceaena. Unlike most Knightias it comes from the 18 inch layer of the Green River Formation that produces a much darker coloration but requires more time to prepare. This specimen is substantially larger than those that come out of the split fish layers at 5.3" long.
It's on a large 8.5x6.1" piece of matrix but we can trim it down upon request for no charge. It comes with an acrylic display stand.

About Knightia
Knightia is an extinct genus of small, schooling, ray-finned fish related to modern herrings and sardines. Abundant in the warm freshwater lakes of the Eocene Green River Formation, they fed on insects, plankton, and tiny fish, while serving as prey for nearly every larger predator in the ecosystem. The most common species, Knightia eocena, reached about 15 cm in length and is celebrated today as the state fossil of Wyoming.
These streamlined fish are recognized by their heavy scales, small conical teeth, and rows of dorsal and ventral scutes along the body. Their fossils are among the most iconic from the Green River Formation—an exceptional 48-million-year-old lake deposit in Wyoming, Colorado, and Utah known for preserving a remarkably detailed snapshot of ancient life in a warm, lake-rich Eocene landscape.
