English: Size comparison of the theropod-shaped pseudosuchian archosaur Effigia okeeffeae, with the silhouette scaled based on the 17 cm (6.7 in) skull, which results in a length matching the estimated 2 m (6.6 ft). The human silhouette 180 cm is from File:Silhouette of man standing and facing forward.svg (CC0).
