Best Answer

Psarolepis has features suggesting that it was very closely related to the last common ancestor of the ray finned fish (which today include salmon, tuna, and anchovies) and the lobe finned fish (such as coelacanths and lungfish). Terrestrial vertebrates, in turn, descended from lungfish.
