13.5" Dendrites On Limestone - Utah

This is a large, 13.5" wide section of limestone with manganese dendrites on the surface. While they look like plant fossils they are mineral formations, that often occur between layers of sedimentary rock. These dendrites can be found on both faces of the rock and are quite attractive to look at. This specimen measures 13.5 x 7.8" and weighs just under 12 lbs.

Dendrites that occur within rock are most often a result of intruding (percolating) mineral solutions that contained manganese and/or iron. These solutions can work their way through microscopic cracks in the rock, leaving behind unique branching patterns. To an untrained eye, these can be mistaken for plant fossils within the rock.
