Opisthocoelicaudiinae
Opisthocoelicaudiinae is a clade of titanosaurian dinosaurs from the Late Cretaceous, ranked as a subfamily. It was named by John McIntosh in 1990. Opisthocoelicaudiines are known from China, Mongolia, and the United States. Three genera were assigned to Opisthocoelicaudiinae by Gonzalez et al. (2009): Alamosaurus, Opisthocoelicaudia (the type genus) and Pellegrinisaurus,[2] although only Alamosaurus and Opisthocoelicaudia were found within the group by Díez Díaz et al. (2018).[1] The hands of opisthocoelicaudiines lacked wrist bones and phalanges.[3]
