Bands show 95% confidence ranges for the least-square regression lines for parvipelvian ichthyosaurs except Ophthalmosaurus (n=19), non-avian dinosaurs except sauropods (n=12), and cetaceans (n=8). Eyeball diameters for dinosaurs and ichthyosaurs are based on the external diameter of the sclerotic rings (which were sometimes estimated from the height of the orbit in ichthyosaurs). Data for non-ichthyosaurs were derived from the literature.
