taxon notes

The most extreme development of the palpebral is found in the armored dino- saur Euoplocephalus tutus, where the bone forms a quarter-sphere and adducts to completely occlude the or- bit (Coombs, 1972; Vickaryous and Russell, 2003). Notwithstanding the superficially similar position, palpe- brals and tarsal plates differ both anatomically and developmentally and are not considered homologous (Gauthier et al., 1988)
