| Abstract: |
The present paper is a review of the Eurasian species which can be attributed to the genera <i>Dicynodon</i> and <i>Lystrosaurus (Therapsida: Dicynodontia)</i>. The genus <i>Dicynodon</i> is represented in Scotland, in Russia (Russian platform) and in China (Xinjiang)
it is now known for sure from Laos. The genus <i>Lystrosaurus</i> is represented in India, in Russia (Russian platform) and in China (Xinjiang). The presence of <i>Dicynodon</i> in Laos implies necessarily a land connection between the Indochina block and Pangaea during the Late Permian. The probable existence of <i>Lystrosaurus</i> species which are represented both in Gondwanaland (South Africa, India and Antarctica) and in Xinjiang suggests the hypothesis of a terrestrial route situated East of the Tethys during the Early Triassic.
