First discovery of a primitive coelacanth fin fills a major gap in the evolution of lobed fins and limbs. by Friedman, M, Coates, M, Anderson, P

“…This uncertainty arises from an outstanding gap in our knowledge of early lobed fins: there are no fossil data that record primitive pectoral fin conditions in coelacanths, one of the three major groups of sarcopterygian (lobe-finned) fishes. A new fossil from the Middle-Late Devonian of Wyoming preserves the first and only example of a primitive coelacanth pectoral fin endoskeleton. …”

Initial radiation of jaws demonstrated stability despite faunal and environmental change. by Anderson, P, Friedman, M, Brazeau, MD, Brazeau, MD, Rayfield, E

“…Devonian functional space is dominated by lobe-finned fishes and 'placoderms'; high disparity within the latter implies considerable trophic innovation among jaw-bearing stem gnathostomes. …”
