Ichthyostega is an extinct genus of early tetrapod that lived during the Late Devonian period, around 366 million years ago. It is considered one of the first vertebrates to have successfully transitioned from water to land, representing an important step in the evolution of vertebrates from aquatic to terrestrial environments. Ichthyostega had both fish-like and amphibian-like features, with body adaptations for a semi-aquatic lifestyle.
