Holoptychius-late Devonian period. The Sarcopterygii. are generally robust osteichthyan fishes with fleshy lobe-fins. They are distinguished from the Actinopterygians or ray-finned fish by their muscular fins with articulating bones.The fins are called lobe fins because they are fleshy and like the limbs of land animals, rather than the fins of familiar ray-finned fish.The lobe fins swivel on a shoulder or hip socket (like a tetrapod limb) and most of the bones can be matched directly to the bones in the limbs of land animals.oloptychius-late Devonian period.
