Livoniana is a genus of prehistoric tetrapodomorphs which lived during the Devonian period (Givetian - Frasnian stages, about 374 - 391 million years ago). [1]
This species is a transitional form between fish and the earliest tetrapods, like Tiktaalik , Ichthyostega and Acanthostega . Before Livoniana there was Elginerpeton and Obruchevichthys .
Four legs developed in water, not on land, to better escape waterliving predatory creatures like Hyneria . There were very lush forests, and particularly swamps, where four limbs became very useful to avoid predators. [2]
