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. 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 123.8âÂÂñ2.0 Ma and 118.5âÂÂñ0.9 Ma of the Barremian-early Aptian.
Trackways of theropods and sauropods have been reported.
