Beyond the game
The real Ichthyostega
Ichthyostega was an early limbed vertebrate with a deep body and a tail retaining a fin. Its skeleton combines features associated with water and the emerging history of movement on land.
Its limb and trunk construction differs from that of a living salamander. The skeleton has been central to studies of how early tetrapods supported and moved their bodies.
