The new Zimbabwean assemblage is on the same paleolatitudinal climatic belt as other Carnian dinosaur-bearing assemblages and has a similar taxonomic composition: (a) the northern Zimbabwean locality geographically links other Carnian dinosaurian localities across southern Pangaea; (b) the new Zimbabwean locality is the oldest definitive dinosaurian locality in Africa, coeval with Carnian dinosaur localities from other parts of the world; (c) summary stratigraphic column of the Pebbly Arkose Formation at the type locality in Zimbabwe showing the records of Mbiresaurus raathi (red), a herrerasaurid dinosaur (yellow), a traversodontid cynodont (blue), a hyperodapedontine rhynchosaur (orange) and an aetosaur (green); (d) representative fossils from the Pebbly Arkose Formation, including (1) aetosaur paramedian osteoderm (dorsal view), (2) herrerasaurid dinosaur coracoid (lateral view), (3) cynodont dentary (lateral view) and (4) hyperodapedontine rhynchosaur maxilla (occlusal view).
