The Early Jurassic sauropod dinosaurs Zizhongosaurus, Barapasaurus, Tazoudasaurus, and Vulcanodon may form a natural group of basal sauropods called the Vulcanodontidae. Basal vulcanodonts include some of the earliest known examples of sauropods. The family-level name Vulcanodontidae was erected by M.R. Cooper in 1984.[1] In 1995 Hunt et al. published the opinion that the family is synonymous with the Barapasauridae.[2] One of the key morphological features specific to the family is an unusually narrow sacrum.
