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 morphology was once used as a basis for the now-defunct taxonomic group Thecodontia.
