RAxML (LGX+ G4m model + I)/ Phylobayes (LG model with CAT approximation)/IqTree/ (LG+ F + R4 model). Black circles indicate full support by all methods used. "–" indicates that the pattern of branching was not recovered by one of the reconstruction methods used. Gray arrow indicates the alterative position of Stratorugosa clade under PhyloBayes analysis. B Tree based on the alignment of 151 protein-coding genes including either Thecochaos (13 898 AA positions) or Stratorugosa sequences (42 744 AA positions) or both, so the 58 gene set is also in.

Figure 7 in Revised systematics of Palaeozoic 'horseshoe crabs' and the myth of monophyletic Xiphosura
Figure 7. Summary cladogram of higher-level relationships retrieved from the phylogenetic analysis. Chelicerata consists of Pycnogonida and Euchelicerata, with megacheirans forming a polytomy on the node below. Trilobites and xenopods form a basal clade which is here considered to represent Antennata. For the full consensus tree see the Supporting information.

Figure 8 in Revised systematics of Palaeozoic 'horseshoe crabs' and the myth of monophyletic Xiphosura
Figure 8. Summary cladogram of the internal relationships of Prosomapoda. Arachnids, eurypterids, and chasmataspidids form a clade, here termed Dekatriata. Xiphosurans are paraphyletic with respect to Dekatriata, with xiphosurids forming a monophyletic clade of their own. All taxa outside the two labels are synziphosurines, which would here be polyphyletic. For the full consensus tree see the Supporting information.

Specimen ELM G1:262:2, clearly showing the partially reduced pre-opercula tergite of somite VII (arrowed) between the downturned carapace and the hypertrophied tergite of somite VIII. Scale bar = 10 mm. B, 'Eurypterus' stoermeri Novojilov, 1959, a chasmataspidid from the early Devonian (Lochkovian) of Siberia, Russia. Specimen PIN 1138-1, exhibiting the microtergite of somite VII (arrowed) positioned between the carapace and the buckler. The microtergite curves anteriorly towards its lateral edges, and is particularly noticeable on the left-hand side. The occurrence of ridges associated with the lateral eye on the carapace is also labelled. Image courtesy of Dave Marshall. Scale bar = 2 mm.
