Dendrite Crystal Sandstone - SOLD 7.32" giftsscientists Coupled with their hydrodynamic shellsThough they may look like fossil plants, dendrites are incredible and inorganic formations that occur solely due to interactions between physics and geochemistry. These branching patterns are made of manganese oxides and commonly form on the surface of sandstones. As the manganese cools, it crystalizes into thin, tree like shapes in the same process that creates snowflakes. This specimen is a 7. 32" sandstone showcase piece that has been imprinted
