Acrodont - Wikipedia
Acrodonty (from Greek akros 'highest' [1] + odont- 'tooth') is an anatomical placement of the teeth at the summit of the alveolar ridge of the jaw, without sockets, [2] characteristic of bony fish. Functionally, acrodont tooth implantation may be related to greater bite force. [3] .

2017年12月6日 · Acrodonty, where the tooth attaches to the apex of the jawbone, is an unusual form of tooth attachment that has been associated with the highly autapomorphic condition of monophyodonty. Beyond Lepidosauria, very little is known about the relationship between acrodonty and monophyodonty in other amniotes.
