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]
Thecodontia (meaning 'socket-teeth'), now considered an obsolete taxonomic grouping, was formerly used to describe a diverse "order" of early archosaurian reptiles that first appeared in the latest Permian period and flourished until the end of the Triassic period. All of them were built somewhat like crocodiles but with shorter skulls, more ...
An animal's dentition for either deciduous or permanent teeth can thus be expressed as a dental formula, written in the form of a fraction, which can be written as I.C.P.M I.C.P.M, or I.C.P.M / I.C.P.M. [10] [11] For example, the following formulae show the deciduous and usual permanent dentition of all catarrhine primates, including humans:
In the late nineteenth century, the theory became popular that such remains belonged to carnivorous prosauropods: animals with the body of Thecodontosaurus, but with slicing teeth. In 1890, Arthur Smith Woodward accordingly named a Thecodontosaurus platyodon, [ 7 ] and in 1908 Friedrich von Huene named a Thecodontosaurus cylindrodon . [ 8 ]
The dentition of Cymbospondylus is generally thecodont, meaning that the tooth roots are deeply cemented into the jawbone. However, not all species share the same robustness in terms of their dental implantation. C. petrinus has a particular form of thecodont dentition, its teeth appearing to be fused at the bottom of the alveoli. [70]
