Shinekhudag Formation Explained

Shinekhudag Formation
Type:Geological formation
Region:Dundgov
Country:Mongolia
Underlies:Khukhtek Formation[1]
Overlies:Tsagaantsav Svita
Period:Valanginian

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]
