The Griman Creek Formation is a geological formation in northern New South Wales and southern Queensland, Australia whose strata date back to the Albian to Cenomanian. Dinosaur remains are among the fossils that have been recovered from the formation.[1]
Vertebrate paleofauna
Indeterminate avialan, euornithopod, and sauropod remains that were once misidentified as brachiosaurid are present in New South Wales, Australia.[1] Euornithopod tracks are also present in New South Wales.[1]
