Table 4 Comparison of supinator and pronator muscles in the coelacanth (Latimeria), Australian lungfish (Neoceratodus) and mudpuppy (Necturus)

From: Comparative pelvic development of the axolotl (Ambystoma mexicanum) and the Australian lungfish (Neoceratodus forsteri): conservation and innovation across the fish-tetrapod transition

Latimeria chalumnae Neoceratodus forsteri Necturus maculosus
Fourth pronator “4 ième pronateur “ (dorsal) O: posterior edge of the process on the fourth axial element I: Base of the last few preaxial lepidotrichia Lepidotrichial flexors (Dorsal)) O: Lateral sides of fin elements I: Lepidotrichia    
Fifth pronator “5ième pronateur” (dorsal) O: posterior edge of the process on all postaxial elements surrounding the fourth axial elementI: base of all post-axial lepidotrichia       
Supinator, second layer, group 3. “Supin couche 2, groupe 3” O:Posterior edge of all four axial elements.I: Preaxial radials and preaxial lepidotrichia. Lepidotrichial flexors (Ventral) O: Lateral sides of fin elements I: Lepidotrichia    
Supinator, second layer, 4th group “Supin, couche 2, groupe 4” O: Posterior edge of the fourth axial element. I: Postaxial lepidotrichia       
Latimeria chalumnae Neoceratodus forsteri Necturus maculosus
Supinator, second layer, group 3 “Supin, couche 2, groupe 3” O: Posterior edge of all four axial elements.I: Preaxial radials and preaxial lepidotrichia. Radial-axial (Ventral and dorsal ) O: All axial elementsI : All radial elements    
Supinator, first layer. “Supin, couche1 ” O: postaxial region between the base of the mesial hypophysis (anteriorly) and the arcuate ridge (posteriorly)I: through a tendon to the preaxial radials and preaxial lepidotrichia       
Supinator, second layer, group 2 “Supin couche 2, groupe 2 ” O : postaxial side of the arcuate ridgeI: Preaxial radials and preaxial lepidotrichia.       
       Popliteus (pronator and supinator) (Ventral) O: Underside of the femur near the insertion of the puboischiofemo-ralis externus)
