Asiamericana (AY-zha-MER-i-KAHN-a – ( Greek: Asia meaning Asia and New Latin Americas meaning Americas) is a dubious fossil fish genus known only from isolated teeth. It was named to recognize the occurrence of similar fossil teeth in Central Asia and North America. These regions once formed a connected land mass, during the Cretaceous period and were referred to as Asiamerica.
The teeth were discovered by L. A. Nesov in 1995. The findings were based on three teeth found in the central Kyzylkum desert, Uzbekistan, in deposits of the Bissekty Formation, dated to the mid-late Turonian age of the Late Cretaceous, about 90 million years ago. They are comparable to other teeth found in Kazakhstan and North America, which have been illustrated but not formally described. The type species is A. asiaticus.
The teeth themselves are straight, lack a constriction at the base, and lack serrations.
