Volkheimeria (meaning "of Volkheimer") was an eusauropod[1] sauropod dinosaur. It lived during the Middle Jurassic, approximately 160 million years ago. Fossils of Volkheimeria have been found in the Cañadón Asfalto Formation of the Cañadón Asfalto Basin in Patagonia, Argentina. The type (and only known) species, V. chubutensis, was described by José Bonaparte in 1979. Volkheimeria is known from some incomplete postcrania, including a mostly complete pelvis and sacrum, caudal vertebrae and a femur and tibia.[2] Many features of this scant material can distinguish Volkheimeria especially in the pelvic and vertebral regions, such as the very low flat neural spines.[3]

Discovery and naming

Volkheimeria was first described in 1979 by Jose Bonaparte. In the paper, Bonaparte also named its type species, V. chubutensis. It was also shown to be a relative of Lapparentosaurus by Bonaparte due to similarities in the neural laminae. Originally identified as a possible cetiosaur along with Patagosaurus and then identified as a brachiosaur for a time, Volkheimeria is now considered a eusauropod along with Patagosaurus and Lapparentosaurus, with Volkheimeria and Lapparentosaurus relatively primitive eusauropods compared to the more derived Patagosaurus. The only known specimen of Volkheimeria is from the Callovian to Oxfordian aged Patagonian deposits that also preserved Patagosaurus and Piatnitzkysaurus, both named in the same publication as Volkheimeria.[3]
