The Zagaje Formation is an Early Jurassic Epoch (Hettangian-Sinemurian) geologic formation located mostly in Poland with layers also exposed in north Germany. This unit is known for its diverse Ichnofossil assemblages, with traces of invertebrates along vertebrate footprints. Indeterminate fossil ornithischian tracks, of the Hettangian Stage, have been reported from the formation.[4] The Zagaje Formation correlates with The lower part of the Höganäs Formation in Scania, as well the Munkerup Member and the Gassum Formation in Denmark.[1]
