Phylogenetic relationships of
Foreyia maxkuhni
gen. et sp. nov. and developmental origin of the derived characters. (
A
) Strict consensus trees of the 259 most parsimonious trees of 317 steps (CI = 0.3817, RI = 0.6766) with some of the uniquely derived characters present in
Foreyia maxkuhni
on the left, and reconstructions of genera with atypical general morphology. (
B
and
C
) Shared features of
Ticinepomis peyeri
and
Foreyia maxkuhni
(in orange) not included in the cladistics analysis (see main text for numbers). (
D
) Reconstruction of a coelacanth embryo with localization of embryonic tissues that give rise the derived skeletal features present in
Foreyia
. It is hypothesized that changes in the expression of
Pax9
may have altered the derived characters shown in blue on the reconstruction (
E
). All the drawings were made by LC. Abbreviation: Boc, basioccipital; Cla, clavicle; Exo, exoccipital; lat. Meso., lateral mesoderm; neur. cr., neural crest; pect. f., pectoral fin; S (numbered), somite.
