Wonthaggi Formation

The Wonthaggi Formation is a geological formation in Victoria, Australia whose strata date back to the Early Cretaceous. It is part of the Strzelecki Group. Dinosaur remains are among the fossils that have been recovered from the formation.[1][2] It is partially equivalent to the Eumeralla Formation.

Dinosaur Cove has moved north over the last hundred million years[3]

Indeterminate ornithopod remains are present in Victoria, Australia.[4] Indeterminate megaraptorid remains are present in Victoria, Australia.[5] The formation also provided fossils of Koolasuchus cleelandi.[6]
