Figure 5.3 Primitive coelacanths are in light blue and the anatomically modern coelacanths
including the extant Latimeria are in red. Euporosteus is positioned either crownward of
Diplocercides or as its sister taxon, indicating that the distinctive body plan of anatomically
modern coelacanths must have been established no later than 409 Mya. Euporosteus also lends
support to the possibility that Eoactinistia may represent an early member of the anatomically
modern coelacanths with the dentary sensory pore. Abbreviations : Eif, Eifelian; Giv, Givetian;
Loc, Lochkovian; Pr, Pragian.
