Is the caudal fin a primitive fin?

The heterocercal caudal fin is found in a diversity of fish clades and is believed to be primitive for sharks and ray-finned fishes ( Figs. 1E, F, 2) despite considerable diversity in the morphology of tail shapes in fossil fishes (see Moy-Thomas and Miles, 1971 ).

Their lightweight skeleton along with the oil-filled liver provides buoyancy against the heavy body.
