Notes specific to this specimen: An absolute stellar specimen! There were only a few specimens recovered that showed such abundance and contrast. This particular horizon we called “Grypania Heaven” due to its stellar appearance. This super-rich slab is populated with dozens of showy and very distinct Grypania, many with characteristic curvature and arcs. In addition, some of the specimens have desiccation distortion along the sheath
