The Opisthocoelicaudiinae is a clade of titanosaurian dinosaurs from the Late Cretaceous, ranked as a subfamily. Opisthocoelicaudiines are known from China, Mongolia, and the United States (New Mexico, Texas, and Utah).[1] Three genera have been assigned to Opisthocoelicaudiinae: Alamosaurus, Borealosaurus, and Opisthocoelicaudia (the type genus).[3] It was named by John S. McIntosh in 1990.[1] The hands of opisthocoelicaudiines lacked wrist bones and phalanges.[4]
