Sulestes
Sulestes was a genus of deltatheroidean mammal from the Cretaceous Period. Its type species is S. karakshi. The known specimens were found in the Bissekty Formation, Kyzyl Kum desert, Uzbekistan. Sulestes was the first and currently only identified metatherian taxon from the Bissekty Formation.
Its autapomorphies include the first premolar's oblique orientation relative to the dentary, an asymmetrical third molar, the presence of a fourth non-vestigial molar, and a double-rooted first premolar.
Sulestes is known from its holotype, a left maxilla fragment, as well as referred specimens. These specimens were originally labelled under "Deltatherus" and "Marsasia" and consist of a right petrosal, right maxilla, two left maxilla fragments, left coronoid process, several right and left dentary fragments, and a few isolated teeth. Sulestes is recovered as the sister taxon to Deltatheroides and Deltatheridium within Deltatheroida.
