A number of rhipidistian fish are know which are closely
related to amphibians.
There are a number of rhipidistians which show great similarities to the
early amphibians. Although Eusthenopteron is perhaps the best known, there
are some that were even closer to amphibian lineage. Panderichthyes is
closer still in its skull characteristics and the solidification of its
vertebrae. Elginerpeton, Ventastega, Obruchevichthyes, and Metaxygnathus,
although represented by incomplete fossils, seem to be even closer to
the origin of amphibians although they retain sarcopterygian features
such as large teeth in the coronoid bone of the lower jaw, outside the
row with the rest of the teeth. They both had tetrapod-like girdles (shoulder
and hip) and Elginerpeton had tetrapod-like limb bones (and probably had
toes) (Ahlberg, 1995; Carroll, 1988).
