*"T. hoffeti" Allain "et al.", 1999 (type"Tangvayosaurus" is a
genus ofsauropod dinosaur from theAptian -Albian ageLower Cretaceous Grès Supérior Formation ofSavannakhet ,Laos . It was a basaltitanosaur , and is known from the remains of two or three individuals.It is based on TV4-1 to TV4-36, consisting of a partial
pelvis , several backvertebra e and a tail vertebra, ribs, and an upper arm bone (humerus ). Another skeleton includes 38 tail vertebrae, a neck vertebra, and most of a hind limb. Thetype species , "Tangvayosaurus hoffeti", was described by a group of a dozen scientists led by Ronan Allain in 1999. Allain "et al." also referred the old species "Titanosaurus " "falloti", from the same formation and based on partial thigh bones and tail vertebrae, to their genus as "T. sp."cite journal |last=Allain |first=R. |coauthors=Taquet, P.; Battail, B; Dejax, J.; Richir, P.; Véran, M.; Limon-Duparcmeur, F.; Vacant, R.; Mateus, O.; Sayarath, P.; Khenthavong, B.; and Phouyavong, S. |year=1999 |title=Un nouveau genre de dinosaure sauropode de la formation des Grès supérieurs (Aptien-Albien) du Laos |journal=Comptes Rendus de l'Académie des Sciences à Paris, Sciences de la Terre et des Planètes |volume=329 |pages=609–616 |language=French ] The most recent review tentatively retains the genus because it is different from the only other established sauropod from the same approximate time and area ("Phuwiangosaurus "), but disagree with adding "T. falloti" to it.cite book |last=Upchurch |first=Paul M. |coauthors=Paul M.
