The inferred sclerotic ring for the Stan specimen is ~7 cm (2.8 in) in diameter with an internal aperture diameter of ~3.5 cm (1.4 in). Based on eye proportions in living reptiles, this implies a pupil diameter of about 2.5 cm (0.98 in), an iris diameter about that of the sclerotic ring, and an eyeball diameter of 11–12 cm (4.3–4.7 in).
