Fig. 1 in Morphological diagnoses of higher taxa in Ophiuroidea (Echinodermata) in support of a new classification

Fig. 1. Summary phylogenetic tree of the ophiuroid higher taxonomy. Modified from O'Hara et al. (2017: fig. 1), with Ophiobyrsidae included based on O'Hara et al. (2017: fig. S3) sample Ophiuroidea_ sp_IE.2009.1713 (= Ophiophrixus_confinis) and additional unpublished exon-capture data on samples Ophiobyrsa_rudis_F222711 and Ophiosmilax_sp_IE.2207.6967. All-sites PLRS/RAxML tree with node support and age confidence intervals (coloured bars). Node support shows all-sites RAxML BS followed by the proportion of the data subset trees in agreement. For all other nodes support was 100/1. The root was fixed according to O'Hara et al. (2014) at 270 Ma.
