Corriebaatar
Corriebaatar is the type and only genus of Corriebaataridae, a family of multituberculate mammals. It contains the single species Corriebaatar marywaltersae and represents the first evidence of Australian multituberculates[1] Fossils found in the Wonthaggi Formation date back to the Aptian stage of the Early Cretaceous.

Discovery
The species Corriebaatar marywaltersae was discovered in 2009 based on the discovery of a well-preserved fourth premolar found in Victoria, Australia at the Flat Rocks fossil site. It was hypothesized to represented a cimolodontan multituberculate mammal as opposed to a new, unrecognized lineage. The 2009 specimen was the holotype and the only known remains of the species until a second specimen of C. marywaltersae was discovered at the same site and reported in 2018. The second specimen was two pieces of the lower jawbone that preserved both the fourth premolar and the first and second molars.[2]
