The curved pencil-like sauropod teeth from the Bostobe Formation (Upper Cretaceous, Santonian-Campanian) of the Shakh-Shakh locality in Kazakhstan are referred to a representative of the Laurasian clade Opisthocoelicaudiidae known from the Upper Cretaceous (Campanian-Maastrichtian) of Mongolia. The teeth are slightly expanded near the apex and have in this part D-shaped cross-section. The enamel sculpturing consists of short longitudinal ridges or enamel is smooth in some parts of the crown. A similar dental morphotype is found in a titanosaur from the Bissekty Formation (Turonian) of Uzbekistan, which also may belong to the Opisthocoelicaudiidae.
