Acrodonty (from Greek akros 'highest'

alveolar ridge of the jaw, without sockets,[2] characteristic of bony fish. Functionally, acrodont tooth implantation may be related to strong bite force.[3]

Squamata: Within squamate reptiles, acrodont tooth implantation is best known in Acrodonta and some species of amphisbaenians, though some snakes are also referred to as being acrodont. Acrodonta is unique in that the name of the clade is based upon this trait. Most other squamate reptiles have pleurodont dentition, though some snakes are occasionally described as having acrodont dentition.[4][5]

Rhynchocephalia: Acrodont tooth implantation is common within

Sphenodon.[6]

Amphibia: Acrodont tooth implantation also present in some

temnospondyl Microposaurus.[7][8][9]
