Abstract: This study reviews the morphology and topological distribution of sesamoid elements in the lizard families Gymnophthalmidae, Polychrotidae, Tropiduridae, Corytophanidae, Teiidae, Scincidae and Gekkonidae. We used cleared and stained specimens of 41 species, and describe 18 sesamoids of both fore and hindlimbs, finding a new sesamoid (fabella lateralis). The toplogical distribution of these elements is compared among lizard families and other vertebrates (mammals, anurans and birds), and we do not find putative synaphomorphies or autapomorphies. We recognize that the intermedium is not yet a clearly defined sesamoid, but state that this is the case for the pisiform.
