In Pennsylvania, a tetrapod that dates 5 million years older than Ichthyostega and Acanthostega is represented by a robust shoulder bone.11 The transition between fish and amphibians (tetrapods) appear in the fossil record some 365 million years ago in Famennian strata.12 Intermediate forms between their fish ancestor,

Roughtly, at the point where lobe-finned fish were, in a sense, effectively equally adapted to both land and water locomotion, is the point at which they are no longer considered to be fish but instead amphibians.
