Bismuth Rainbow Crystal Staircase - 1.597" britishhistory The majority of fossilized Gastornis

The majority of fossilized Gastornis eggshell fragments are found in the Provence region of France

They are all highly polished on both sides and roughly 2" (5cm) in diameter

Due to their reusable design

It’s that thing that’s all around us and has been for over 13 billion years

Our small fossils measure 2-3" and include a variety of smaller fishes

Bismuth Rainbow Crystal Staircase - 1.597" britishhistory The majority of fossilized GastornisBismuth is an element (Bi 83) best known for its unusual staircase shape, the result of bismuth atoms attaching to the edge of a rapidly growing crystal. This is called hoppering, when atoms are drawn to the edge of a structure, creating a lattice formation. This specimen is a Bismuth Rainbow Crystal, measuring 1. 597". While bismuth's practical uses are limited beyond some pharmaceuticals, the element's utterly unique colors and shape continue to
