Actinistia is a subclass of mostly fossil lobe-finned fishes. The tetrapodomorphs had essentially the same anatomy as lungfishes. Organisms and fauna Marine mammals: Urochordata tunicates Ascidiacea sea squirts Appendicularia larvaceans Thaliacea pyrosomes, salps, doliolids.

The fossil records suggests that the Coelacanths peaked case the Carboniferous. Rhipidistia is now understood to be an ancestor for the whole of Superclass Tetrapoda.
