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.
