Fish Fossil - Knightia Eoceana Fluorite A silicone-based mineral closely related

A silicone-based mineral closely related to quartz and agate

Pyrite formations tend to be shiny and metallic

which over the course of millions of years becomes solid while retaining the semitransparent yellowish hue of tree sap

depending on the presence of minerals like manganese or iron during the formation of the crystals

which is a brilliant mineral in the aragonite family known for its twinning crystalline structure and delicate form

Fish Fossil - Knightia Eoceana Fluorite A silicone-based mineral closely relatedDuring the Eocene, 40 50 million years ago, vast shoals of freshwater fish inhabited a large shallow inland sea across the American West. The herring like fish of the genus Knightia were far and away the most abundant freshwater fish during this era, and because of this they are one of the most frequently found vertebrate fossils on earth. Originating from the famed Green River Formation in Wyoming, fossils of Knightia eocaena and their close
