Other dinosaurs also include a titanosaurian sauropod and an ornithopod. "Ichthyovenator" lived alongside sauropod and ornithopod dinosaurs, as well as bivalves, fish and turtles. Further research has found medullary bone in the theropod "Allosaurus" and ornithopod "Tenontosaurus". Further research has found medullary bone in the carnosaur "Allosaurus" and the ornithopod "Tenontosaurus". Zalmoxes is an extinct genus of rhabdodontid ornithopod dinosaur from the Maastrichtian of Romania. "Bakesaurus" is an informal name for an ornithopod dinosaur from the Late Cretaceous of China. The only dinosaur fossil from Central America currently is a femur of an ornithopod. It is thought to have been a herbivorous small ornithopod. "Corythosaurus" was an ornithopod, and therefore a herbivore. Morrison ornithopod trace fossils are represented by three toed tracks which are generally small. "Dysalotosaurus" was a small, relatively basal iguanodontian ornithopod. "Qantassaurus" is a basal iguanodont ornithopod that was originally assigned to the Hypsilophodontidae. The bone is the northernmost record of an ornithopod in South America. If so, "Hypsilophodon" would have been the only known armoured ornithopod. Undescribed ornithopod is present in the Wucaiwan member.
