Acrodonta are a subclade of iguaniansquamates consisting almost entirely of Old World taxa. Extant representation include the families Chamaeleonidae (chameleons) and Agamidae (dragon lizards), with at least over 500 species described. A fossil genus, Gueragama, was found in Brazil, making it the only known American representative of the group.[1]
The group is eponymously named from their acrodont dentition, whereby the teeth are consolidated with the summit of the alveolar ridge of the jaw without sockets.[2] There are, however, other animals that have acrodont dentition such as tuataras.[3]
SystematicsEdit
Usually acrodonts are divided into two families Chamaeleonidae and Agamidae, there are a few studies that suggest chameleons are nested within Agamidae.[4][5] In order to maintain the familial status of Chamaeleonidae some authors suggested placing the clades Uromastycinae and Leiolepidinae in a third family Leiolepididae.[4][5] However a majority of papers concerning acrodont phylogenetics support the traditional dichotomy of the group.[6][7][8][9]
Below is the phylogeny of the acrodont lineages after Pyron et al. (2013):[8]
