Stratigraphical distribution of known dinosaurian fauna across the Wessex Formation spread, split into the three dinosaurian clades: theropods, ornithischians and sauropods to determine faunal assemblage diversity and sympatry across the Wessex Formation (see supplementary material for full details of taxa locations). The black silhouette represents the stratigraphical location of Invictibellatrix. Silhouettes by Daniel D. Folkes.
