Fish Fossil - Knightia EoceanaDuring 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

Colored fluorite clusters atop candle quartz bases are some of the most distinctive mineral specimens to originate from the mines of Inner Mongolia

An absolutely remarkable show piece that has a dramatic ability to catch light on two levels

from fine crystal to botryoidal (spherical/nodular)

and the second most common form of Calcium Carbonate on Earth

and as a precious metal for thousands of years

large calcite crystals and the dusting of fine gold from the pyrite is unique to specimens from this specific region of China and have not been found anywhere else

and is one of the more common gems although pieces of exceptional hue and clarity are considered fairly rare and can be extremely valuable

creating a striking and colorful contrast

where some truly impressive specimens like this very rarely emerge from the mines
