Marsupials from the Late Cretaceous of Uzbekistan. Acta Palaeontologica Polonica 44: 71–81

A fragment of dentary with m4, showing characters of some Late Cretaceous North Ameńcan marsupials, is assigned to Marsasia sp. Marsasla Nessov, 1'997 from the Coniacian of Uzbekistan, represented by M. aenigma known from edentulous dentaries with inflected angular processes, was attributed by Nessov to?Marsupialia. Marsasia sp., found in the same horizon as the type species, resembles it in size and structure of the masseteńc fossa, but dffiers in having a less steep coronoid process. We assign Marsasia to Marsupialia on the basis of the following characters: inflected angular process, shape of the dentary similar to that in Asiatheriutn, postcanine dental formula, infened from alveoli for p1-3, mL-, and sfructure of m4 more similar to Cretaceous mźrrsupials than eutherians. The phylogenetic position of Marsasia may be between the Albian Kokopel-liaandCampanianAsiatherium. Marsasiais tentatively referredto the orderAsiadelphia, which may represent an endemic Asian marsupial clade
