Dendrite Limestone (sometimes called picture stone or painted stone) is an amazingly original work of art by Mother Nature. The patterns occur naturally due to the presence of iron and manganese oxide Dendrites. Dendrites are the branch-like formations of manganese oxide crystallizing within the limestone. A dendrite is a superficial deposit of manganese oxide that has crystallized in a multi-branching tree-like pattern. This pattern is what fools us into thinking they are plant fossils. Dendrites form as water rich in manganese and iron flows along tiny cracks between layers of limestone and other rock types.
