Stegocephalia
Extracted from the Wikipedia article Stegocephali.
Stegocephali (or Stegocephalia, from Ancient Greek: στεγοκεφαλια, lit. "roofed head") is a clade of vertebrateanimals containing all fully limbedtetrapodomorphs. It is equivalent to a broad definition of the superclassTetrapoda: under this broad definition, the term "tetrapod" applies to any animal descended from the first vertebrate with four limbs each with digits in the extremity (pentadactyly), rather than fins of their sarcopterygian relatives.
