Sarcopterygii

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:

• Coelacanthimorpha
  • Coelacanthiformes
• Dipnoi
  • Ceratodontimorpha
• Tetrapoda
  • Amniota
    • Mammalia
    • Sauropsida
  • Amphibia
    • Batrachia
    • Gymnophiona

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.
