What group of organisms evolved from the same ancestors as amphibians?

According to the Theory of Evolution, all organisms have a shared ancestry.
Also, amphibian is a term that can be used to indicate a particular property (ie. coldblooded organism living both on land and in water) that may belong to groups of organisms stemming independently from divergent clades. Used in this sense amphibians are a paraphyletic group. The term amphibian can also be used to indicate a member of the clade Amphibia, a monophyletic grouping within cladistics.
The most recent ancestor common to Amphibia and Reptilia (which would include Mammalia, under the monophyletic usage) would have belonged to the clade of Tetrapoda. This means that both Amphibia and Reptilia (including Mammalia) are Tetrapoda.
