Dendrite Stone

Dendrites look like fossils, but they are not the remains of living things. Dendrites are made of dark Manganese minerals, usually that form in a branching pattern. Dendrites are found between the layers of stratified rocks, as in this Utah sandstone, and within bodies of Agate. Dendrites or Moss Agate are very popular gemstones.
