Polyglyphanodontia, also known as the Borioteiioidea, is an extinct clade of Cretaceous lizards. Polyglyphanodontians were the dominant group of lizards in North America and Asia during the Late Cretaceous.
== Chronology and distribution == Most polyglyphanodontians are Late Cretaceous in age, with the highest diversity in the group being known from East Asia. The oldest polyglyphanodontian, Kuwajimalla kagaensis, is known from the Early Cretaceous Kuwajima Formation of Japan. The majority of known members of the group inhabited Laurasia; the group also included Gondwanan taxa Bicuspidon hogreli from the Kem Kem Beds of Morocco, Cryptobicuspidon pachysymphysealis from the Quiricó Formation of Brazil and Calanguban alamoi from the Crato Formation of Brazil, while Early Cretaceous South American taxon Tijubina, and possibly also Olindalacerta, might also fall within Polyglyphanodontia or be closely allied to the group. The group became extinct during the end-Cretaceous extinction event, the only major terrestrial squamate group to do so.
