The Shinekhudag Formation (also known as Shinekhudug Formation, Shinekhudag or Shinekhudukskaya Svita) is a geological formation in Dundgov, Mongolia whose strata date back to the Early Cretaceous. Dinosaur remains have been recovered from it.Weishampel, David B; et al. (2004). "Dinosaur distribution (Early Cretaceous, Asia)." In: Weishampel, David B.; Dodson, Peter; and Osmólska, Halszka (eds.): The Dinosauria, 2nd, Berkeley: University of California Press. Pp. 563-570. . It has classically been considered Aptian-Albian in age. Khand et al. (2000) suggested that the age of formation is Berriasian-Hauterivian based on ostracod biostratigraphy. But, Hasegawa et al. (2018) suggested Shinekhudag Formation was deposited between 123.8 ±2.0 Ma and 118.5 ±0.9 Ma of the Barremian-early Aptian.
