Rauhut, O.W.M. (2006). A brachiosaurid sauropod from the Late Jurassic Canadon Calcareo Formation of Chubut, Argentina. Fossil Record 9: 226-237.

Abstract: \\\\\\\"Fragmentary sauropod remains from the Late Jurassic (Tithonian) Canadon Calcareo Formation of Chubut, Argentinean Patagonia, are derived from a taxon of large size, but with very slender forelimbs. The characters of the caudal vertebrae, such as anteriorly placed neural arches, slender forelimbs, and large deltopectoral crest of the humerus indicate that this material represents the first brachiosaurid sauropod reported from South America. This occurrence confirms an almost global distribution of brachiosaurids in the Late Jurassic and thus indicates a rapid diversification and dispersal of this group after its origin, presumable in the late Middle Jurassic.\\\\\\\"

Due to the fragmentary nature of the material this new Patagonian brachiosaurid isn\\\\\\\'t named,
