Bismuth Rainbow Crystal Staircase - 1.845" rockinaboxdendrite Pachycephalosaurus was a Late Cretaceous

Pachycephalosaurus was a Late Cretaceous dinosaur with a unique feature: its skull had a battering ram like bone plate

an ancient and almost alien environment is home to organisms who have never seen the sun

This is one reason that pallasite formation is such an active topic in the scientific community

Bismuth Rainbow Crystal Staircase - 1.845" rockinaboxdendrite Pachycephalosaurus was a Late CretaceousBismuth 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. 845". While bismuth's practical uses are limited beyond some pharmaceuticals, the element's utterly unique colors and shape continue to
