The Mackunda Formation is a geological formation in Queensland, Australia whose strata date back to the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.[1] It consists primarily of interbedded and cross bedded greensand, with variably calcareous shale, with local ferricrete.[2]
