Sarcopterygii is traditionally the
class of lobe-finned
fishes, consisting of
lungfish and
coelacanths. Some taxonomists include the subclass
Tetrapoda, which in turns consists of all the four-limbed
vertebrates, such as
reptiles.
This level of taxonomy is in flux however; the membership of Sarcopterygii is likely to change, and it may even be discontinued as a classification.
