THE earliest evolution of the chordates and their relationships with other deuterostomes remains controversial1–3. Rejuvenation of interest in the areas of molecular phylogeny4 and developmental genetics5–7 has not been matched by new insights from the fossil record, which for the Lower and Middle Cambrian remains exceptionally sparse. The supposed chordate Emmonsaspis8 has been shown to be a frond-like fossil9, and phosphatic sclerites of hadimopanellids, once compared with vertebrate dermal… Expand
