Endoskeletal morphologies of selected gnathostome species. For each taxa, anterior is up. (First column) top, catshark - Scyliorhinus canicula; middle, shark Hemiscyllium ocellatum, bottom, shark Centroscymnus owstoni; (second column) top, lobe-finned fish fossil Sauripteryus, middle, lobe-finned fish fossil Panderichthys, bottom, coelacanth, Latimeria; (third column) top, ray-finned paddlefish Polyodon, middle, ray-finned zebrafish Danio rerio, bottom, ray-finned fish Polypterus, top, pantropical spotted dolphin Stenella attenuate, middle, mouse Mus musculus, bottom, chicken Gallus gallus. Not to scale. Shaded region represents animals with limb skeletons putatively containing incipient or definitive forms of the Gal1-Gal-8 patterning network. Catshark, mouse, paddlefish and zebrafish redrawn from [53]; Hemiscyllium and Centroscymnus redrawn from [54]; Sauripteryus, Panderichthys and chicken from [18]; coelacanth redrawn from [55]; dolphin redrawn from [56]; Polypterus based on [57]
