Shinekhudag Formation

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.[2][3] It has formerly been considered Aptian-Albian in age, but more recent research suggests an earlier Berriasian-Hauterivian age.[4]
