Fig. 3. A. Evolutionary tree of the Ophiacanthidae based on the reweighed dataset tree of Fig. 2B. Calibration is based on nodes marked as 1 (oldest occurrence of small tentacle pores, Europacantha paciphila sp. nov. from the Anisian of Hungary) and 2 (oldest occurrence of lateral arm plate morphology exclusively found in the Ophiomitra-Ophiocamax clade, Reitneracantha dissidens sp. nov. from the late Sinemurian to early Pliensbachian of Austria), and on the first occurrences of a number of extinct genera (Leadagmara Thuy et al., 2012, Dermocoma Hess, 1964, Inexpectacantha Thuy, 2011). Thick lines indicate the observed fossil record of the actual genus, doted lines denote the fossil record of a genus within the same lineage (e.g. Lapidaster sp. nov. in Ophiologimus H.L. Clark, 1911), and thin lines are the expected ranges. B. Relative abundances of the Ophiacanthidae in shallow (<200 m palaeodepth, small dots) and deep (> 200 m palaeodepth, asterisks) environments through time.
