cynodont /ˈsʌɪnə(ʊ)dɒnt /nounA fossil carnivorous mammal-like reptile of the late Permian and Triassic periods, with well-developed specialized teeth.- Suborder Cynodontia, order Therapsida: several families.
By Early Triassic times, cynodonts had diverged into large predaceous carnivores such as Cynognathus and moderate large omnivorous and herbivorous types such as Trirachodon and Diademodon....- Evidence for therapsid fur centers on the presence of infraorbital pits and ridges in some lower Triassic cynodonts.
- Probably the most informative analysis of mammal-like reptiles as transitional forms is the one which focuses, in detail, on the presumed changes from advanced cynodonts to the earliest mammals.
Origin Late 19th century: from Greek kuōn, kun- 'dog' + odous, odont- 'tooth'. |
