Kyzyl Kum
Sultanuvaisia is an extinct genus of ichthyodectiform teleost ray-finned fish from the Late Cretaceous of Kyzyl Kum, central Asia. It was named by Lev Nesov in 1981. At first, he tentatively described the fossil material as jaw fragments of a ctenochasmatid pterosaur (a flying reptile), but reinterpreted "Sultanuvaisia" as a fish in 1986. The type species is "S. antiqua".
