Titanosaurs are the best known sauropods ranging from the medium sized Saltasaurus to gigantic Argentinosaurus. Some or all the titanosaurs may have had armor.  Diplodocids are also present. Sauropods show a wide adaptive radiation filling the medium and large plant eating niches evolving armor, dental batteries even keratinous beaks. Ornithischians seem to be limited to small to medium basal iguanodonts Gasparinisaura, Loncosaurus) and ornithopods.
