This image is from the National Science Foundation, a U.S. Government agency to fund [[science]]. While reconstructions such as this one appear to show what the [[species]] in question really looked like, the true appearance of ''Tiktaalik'' is unknown. For example, the difference in appearance between the head and the "shoudler" area is speculative. So is the implication in the image that ''Tiktaalik'' walked on land. It is just as likely that it used its robust fins to "walk" on the sea floor, helping it to catch prey in an alligator-like manner. While the tail is included in the image, the tail and rear fins have not been found.
