Fig. 10 in Ordovician opabiniid-like animals and the role of the proboscis in euarthropod head evolution

Fig. 10 | Simplified results of phylogenetic analyses and a putative pathway of evolution of key head characters within the euarthropod lower stem group. Dotted lines indicate nodes where some analyses resolved polyphyletic or paraphyletic relationships. Full phylogenetic results provided in Supplementary Figs. 6–11.
