English: Size comparison of the Devonian sarcopterygian Tiktaalik, within unknown regions based on the related Elpisostege. The silhouette was scaled to the largest mandible (31 centimeters (12 in) long), falling within the range of published estimates (1.25–2.75 meters (4.1–9.0 ft)). The human silhouette is from File:Silhouette of man standing and facing forward.svg (CC0).
