Figure 5. Carapace to opisthosoma ratios (C: O) of all eight Carboniferous thelyphonid species [body fossils; does not include full-body impression (trace fossil) Inmontibusichnus charleshenryturneri, see text]. Green boxes represent the opisthosoma (including pygidium but excluding telson) and purple boxes represent the carapace, relative to each other. Measurements only included complete specimens. Averages were taken when data for multiple specimens of a single species were available.
