26. Batrachians (salamanders and frogs) have simplified skulls, with dermal bones appearing rudimentary compared with fossil tetrapods, and open cheeks resulting from the absence of other bones

27. The Anuran skull is notable for the relatively few elements it contains: elements typically present in tetrapod skulls have been lost, or fused with adjacent structures

28. In other words, this animal, though clearly a tetrapod, was primarily an aquatic creature whose immediate forerunners were essentially fish that had never left the water.

29. The fin-limbs of sarcopterygiians are so like the expected ancestral form of tetrapod limbs that they have been universally considered the direct ancestors of land vertebrates.
