Summary
| Description |
English: Fig. 3. 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. |
