Abstract

Arising from J. Liu et al. Nature 470, 526–530 (2011)10.1038/nature09704 ; Liu et al. reply Liu et al.1 described an ‘armoured’ lobopodian, Diania cactiformis, from the Chengjiang Lagerstätte (China; Cambrian, stage 3); this fossil bears potentially arthropod-like articulated and possibly sclerotized appendages, but lacks a sclerotized body. A cladistic analysis resolved Diania as sister-taxon to arthropods. From this phylogenetic position the authors tentatively inferred that arthropodization (sclerotization of limbs) may have preceded arthrodization (sclerotization of body elements) in arthropod evolution. Although we concur with the reasoning behind this inference, it rests on a phylogenetic placement that our analysis of the published data set does not reproduce.
