 Cetiosauriscus greppini: Another species previously in Ornithopsis that was included in Cetiosauriscus, O. greppini was reclassified by Huene in 1929. "Cetiosauriscus" greppini was later renamed again by Huene in 1932 as Cetiosaurus greppini, a junior synonym of "Cetiosauriscus" greppini. "Cetiosauriscus" greppini is from the Reuchenette Formation, a formation of Early Kimmeridgian age. It is known from three individuals, the holotype being the most complete. "Cetiosauriscus" greppini differs from Cetiosauriscus stewarti by having caudal transverse processes that are anteroposteriorly flat and have a distinct dorsal wing-like expansion. It also differs in having anterior posterior centrodiapophyseal laminae situated ventrally from the anterior caudal transverse process, a coracoid with a rounded outline and with a notch ventrally to the glenoid articular face, remarkably straight shafts of humerus and femur, a distal end of the humerus with a higher medial than lateral hemicondyle, a more proximally placed 4th trochanter, and a longer and straighter ischium shaft. These characters certify that both taxa differ on the generic level. The discovery of cartilaginous tissue relatively proximal to the end of the humerus of "Cetiosauriscus" greppini has suggested that the cartilage caps of sauropods may have been larger than predicted by an Alligator CCF and that the cartilage caps extended fairly far onto the metaphysics of some long bones. "Cetiosauriscus" greppini is known from a femur with bite marks on it. The marks strongly match the teeth of Machimosaurus, meaning that Machimosaurus scavenged or possibly regularly preyed on animals like Cetiosauriscus. "Cetiosauriscus" greppini is now considered to be Eusauropoda incertae sedis.
