When more complete specimens of "Cetiosaurus" were described by Phillips in 1871, he finally recognized the animal as a dinosaur related to "Pelorosaurus". However, it was not until the description of new, nearly complete sauropod skeletons from the United States (representing "Apatosaurus" and "Camarasaurus") later that year that a complete picture of sauropods emerged. An approximate reconstruction of a complete sauropod skeleton was produced by artist John A. Ryder, hired by paleontologist E.D. Cope, based on the remains of "Camarasaurus", though many features were still inaccurate or incomplete according to later finds and biomechanical studies. Also in 1877, Richard Lydekker named another relative of "Cetiosaurus", "Titanosaurus", based on an isolated vertebra.
