二齿兽
Dicynodon and other genera, infra-order Dicynodontia, order Therapsida
Example sentencesExamples
- Isolation by desiccation would also explain why dicynodonts - mammallike reptiles that dominate fossil assemblages elsewhere during this time - are conspicuously absent at the site that yielded the two new amphibians.
- The skull is an example of convergent evolution with some of the ornithopods and also with the dicynodonts, an herbivorous group of early synapsids.
- In many dicynodonts the tusks are present in about half of the individuals, indicating that these were probably sexual characters, presumably present in one gender morph and absent in the other.
- One group of therapsids, the dicynodonts, were herbivores with a worldwide distribution.
- The wide diversity of large aetosaurs suggests that they have taken over the role of big herbivore vacated by the trilophosaurs, rhynchosaurs, and dicynodonts with their disappearance from the region at the end of the Carnian.

Origin

Mid 19th century: from modern Latin Dicynodontia (plural), from Greek di- 'two' + kuōn 'dog' + odous, odont- 'tooth'.
