Thecodont dentition is a morphological arrangement in which the base of the tooth is completely enclosed in a deep socket of bone, as seen in crocodilians, dinosaurs and mammals, and opposed to acrodont and pleurodont dentition seen in squamate reptiles. [1] Notably, this appears to be the ancestral tooth condition in Amniota. [2]
This feature is responsible for the name "thecodont" (meaning "socket teeth"), [8] which early paleontologists applied to many Triassic archosaurs.
