Tiktaalik
Tiktaalik is a genus of lobe-finned (sarcopterygian) fish from the Devonian Period found on Ellesmere Island, Nunavut, in Canada’s Arctic Archipelago. A single species is known of Tiktaalik, T. roseae, which lived approximately 385 million years ago. The species was named in 2006 in two articles that described several articulated specimens. These articles set off a storm in the popular press. Titkaalik represents a clear and important evolutionary step in the journey of animals onto land.
