Note: the following dendrogram is a slightly modified version of a dendrogram drawn by CKT for the Palaeos wiki, which itself is based strongly on Dong et al 2004, cladogram, fig 3b; extant priapulids follow Mikko's phylogeny. This phylogeny is certainly less than satisfactory if the hypothesis of paraphyletic Priapozoa and Palaeoscolecida as ancestral ecdysozoans (e.g. Dzik and Krumbiegel 1989, Conway Morris & Peel 2010) , but we have retained it for now pending later revision MAK120422
