The official postcard (of the American Museum of Natural History) says this is a Barosaurus, and that "this unique freestanding mount is the only Barosaurus on view in the world". This was true until the installation of another Barosaurus specimen at the Royal Ontario Museum. The adult specimen pictured is AMNH 6341, classified as Barosaurus lentus. The juvenile specimen (AMNH 7530), originally classified as a juvenile Barosaurus, has since been reclassified as a specimen of Kaatedocus siberi. © Greg from New York, NY, America · CC BY 2.0 · Wikimedia
