A Late Devonian Ichthyostega submerged in a floodplain 365 million years ago in what is today the Canadian Arctic. The tree-like trunk immediately behind the Ichthyostega is the base of a Pleuromeia. The Ichthyostega is eyeing a drowned centipede.. . Ichthyostega was one of the earliest tetrapods, a descendent of lobe-finned fishes and ancestor of amphibians.
