Tiktaalik roseae

Tiktaalik roseae is a species of extinct sarcopterygian (lobe-finned) fishes from the late Devonian period, with many tetrapod-like features. Excellent fossilised forms of the Tiktaalik, which is generally described as the fish that evolved from water dweller to land dweller, were found in 2004 on Ellesmere Island in Canada.
