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

Dinosaurs

Indeterminate dinosaur tracks as well as indeterminate ornithischian tracks are present in Victoria, Australia.[1] Indeterminate euornithopod remains are present in Victoria, Australia.[1] Indeterminate theropod, ornithomimmosaur, and possible indeterminate oviraptorosaur and dromaeosaurid remains are present in Victoria, Australia.[1]
