Panderichthys
Panderichthys is a genus of extinct sarcopterygian (lobe-finned fish). It lived in the late Devonian period, about 380 mya. Possible tetrapod tracks dating back to before the appearance of Panderichthys in the fossil record were found. This suggests that Panderichthys is not a direct ancestor of tetrapods. It shows the traits which evolved during the fish-tetrapod evolution.
