Ichthyostega Säve-Söderbergh, 1932 is an early tetrapod genus living in the Upper Devonian (Famennian) period, 367-362.5 million years ago, and the first to be discovered. Being one of the first animals with legs, arms, and finger bones, Ichthyostega is seen as a hybrid between a fish and an amphibian. Ichthyostega had legs but its limbs probably weren't used for walking as once believed, but were used instead to negotiate its way through the swamps of the time.
