Endosseous labyrinths of the left inner ears of some saurischian taxa derived from surface renderings of CT images, displayed on a cladogram. From left: the basal theropod Herrerasaurus ischigualastensis (MCZ 7063), the basal sauropodomorph Massospondylus carinatus (BP/1/4779), the basal eusauropod Spinophorosaurus nigerensis (GCP-CV-4229), the basal diplodocoid Nigersaurus taqueti (MNN GAD512), the derived diplodocoid Diplodocus longus (CM 3452), the basal macronarian Camarasaurus lentus (CM 11338), the basal titanosauriform Giraffatitan brancai (MB.R.2180.22.1-4), and the titanosaurian Jainosaurus septentrionalis (ISI R162). With respect to that of other sauropods, the vestibular system of Spinophorosaurus is highly remarkable in its elongate semicircular canals and its overall large dimensions (both absolutely and in relation to body size).
