These lovely dendrites grew along a limestone bedding plane. The growth of dendrites is similar to snowflake formation; when a material is below its crystallisation temperature, fractal branches form instead of crystal faces. Dendrites are also a pseudofossil as they can be mistaken for fossil plants.
