Marree Subgroup
The Marree Subgroup, previously described as Maree Formation and Marree Formation, is a geological subgroup in the Eromanga Basin of South Australia whose strata date back to the Aptian. The subgroup was first described as a formation by Forbes in 1966.[2][3] Dinosaur remains are among the fossils that have been recovered from the formation.[1]
