The Hidden Lake Formation is a Late Cretaceous geologic formation in Antarctica. The sandstones and siltstones of the formation were deposited in a deltaic environment.
Intederminate megalosaur remains have been recovered from it.[1] Also many plant fossils and ichnofossils of Planolites sp. and Palaeophycus sp. have been found in the formation.[2]
