Newberyite is a particularly rare and seldom crystallized magnesium phosphate species and this is an exceptional specimen! This piece is a floater, perfect all around, of pale brown translucent, lustrous blades. This hydrated magnesium biphosphate mineral crystallized from bat guano! In other words, it is a mineral produced in nature only after the interaction with biology in the mineral cycle, resulting in the transformation over time of bat poop into an interesting new species of mineral. This is also the Type Locality for the species. Schauss, known for his love of rare species in particular, had a fine thumbnail suite of treasures like this which you normally never see on display!
