Tiktaalik roseae - Late Devonian “Fishapod“ ~ 375 mya

Tiktaalik is an extinct sarcopterygian ‘fishapod’ which evolved during the late Devonian period (~375 mya). Tiktaalik is regarded as an important transitional lifeform, with an anatomy that displays a number of features that indicate a clear linkage between fish and tetrapod (land vertebrate). These anatomical features point to how life may have moved from water onto land. Tiktaalik is thought to have been among the first vertebrates to cross this margin. Paleozoo Evolutionary Models are detailed portraits of some of the first animals to evolve on Earth and they are the work of paleoartist Bruce Currie. More information can be found at
