and possibly additional postcranial material found at Como Bluff. It is now considered a synonym of C. grandis. Morosaurus robustus was named on the basis of an ilium by Marsh in 1878 collected at Como Bluff. It is now considered a synonym of C. grandis. Camarasaurus leptodirus was another one of Cope's Garden Park sauropods and was named in 1879 on 3 partial cervical vertebrae, it has been suggested to be a synonym of C. supremus. Diplodocus lacustris was named by Othniel Marsh in 1884 on the basis of several teeth, a premaxilla, and a maxilla from Morrison, Colorado that were collected by Arthur Lakes and Benjamin Mudge in 1877. Although the teeth and dentary of D. lacustris are Flagellicaudatan, the skull material is likely that of a Camarasaurus. Pleurocoelus montanus was also named by Marsh in 1896 as a new species of Pleurocoelus, the material consisting of several vertebral centra and assorted postcrania of a juvenile individual from Como Bluff. It is generally regarded as a synonym of C. grandis. Uintasaurus douglassi was named in 1919 by W. J. Holland for 5 anterior cervical vertebrae from Dinosaur National Monument, the species was later regarded as a synonym of Camarasaurus lentus. Camarasaurus annae was named by Tage Ellinger based on an anterior dorsal vertebra in 1950. This species is generally considered a synonym of C.lentus. Reassigned species Morosaurus agilis was named in 1889 by Marsh based on a partial skull and 3 vertebrae from Garden Park, Colorado. The species remained in taxonomic uncertainty until in 2020, it was placed in a new genus, Smitanosaurus, and reclassified as a dicraeosaurid. Camarasaurus becklesiii was described as Pelorosaurus becklesii in 1842 by Gideon Mantell based on a partial forelimb from Sussex, United Kingdom. It was placed in Morosaurus by Marsh in 1889 and Camarasaurus by von Huene in 1932 until in 2015, it was placed in its own genus, Haestasaurus. Morosaurus marchei was named by Sauvage in 1898 based on an incomplete distal caudal vertebra and tooth from the Upper Jurassic strata of the Alcobaca Formation of Portugal. Lapparent & Zbyszewski referred the holotype vertebra to Megalosaurus insignis and Madsen et al., 1995 referred it to Megalosauria. The referred tooth was identified as belonging to Turiasauria in 2017. Camarasaurus alenquerensis was named as a species of Apatosaurus in 1957 by Albert-Félix de Lapparent and Georges Zbyweski on a partial postcranial skeleton from Lourinha,
