Neuroanatomy in a middle Cambrian mollisoniid and the ancestral nervous system organization of chelicerates

Here, the authors report a preserved central nervous system in the soft-bodied stem-group chelicerate Mollisonia symmetrica from the mid-Cambrian Burgess Shale. The neuroanatomy described here is proposed to represent the ancestral state for the stem group Chelicerata.
