 The temporal range of Eusauropoda ranges from the early Jurassic to the Latest Cretaceous periods.The most basal forms of eusauropods are not well known and because the cranial material for the "Vulcanodon" is not available, and the distribution of some of these shared derived traits that distinguish Eusauropoda is still completely clear.Eusauropods are long-necked, strictly herbivorous, obligate quadrupedals.
