First Asiatic 'iguanid' lizards in the Late Cretaceous of Mongolia
Magdalena Borsuk-Białynicka and Vladimir R. Alifanov
The first Asiatic records of iguanids are described from the Campanian of Mongolia. The Laurasian origin of the Iguania is therefore equally as likely as the Gondwanan origin, suggested by all previous data. The Asiatic, instead of African provenience of Malagasy 'iguanids', as suggested by Rage (1988), is also possible. Igua minuta gen. et sp. n. and Polrussia mongoliensis gen. et sp. n. are recognized.
Key words: Reptilia, Sauria, Iguanidae, taxonomy, Cretaceous, Gobi Desert.
