Preferred Label : palpebral bone;
Uberon definition : An ossified element investing the upper eyelid.;
Uberon broad term : palpebral;
Uberon Taxon note : 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);
