Abstract [en]

The Museum of Evolution in Uppsala acquired a number of sauropod specimens under the tenure of Professor Carl Wiman. The most intensely studied of these are two partial skeletons, PMU 24705 (formerly PMU R 233) and PMU 24706 (formerly PMU R 234), excavated in Shandong (Shantung) Province, China, by Otto Zdansky, which form the basis for the species Euhelopus zdanskyi. These specimens were acquired by the Museum of Evolution in the 1920s and remain the subject of much interest among sauropod workers. The cranial anatomy, classification and the age of Euhelopus have been the subject of some debate. Other Chinese sauropod material in the Museum of Evolution collection includes three vertebrae (one cervical, one dorsal and one caudal) and an incomplete femur. The caudal vertebra has been recently referred to Diplodocoidea by some researchers and to Titanosauriformes by others. Incomplete sauropod remains, which may represent the topotype material of Alamosaurus sanjuanensis (the only named post-Cenomanian North American sauropod to date) in the Museum of Evolution collection from New Mexico, coupled with specimens from North American museums, may help resolve the validity of A. sanjuanensis as a taxon and the sauropod hiatus as either a real phenomenon or an artefact of the fossil record. The palaeontological significance of the Museum of Evolution's sauropod collection cannot be overstated. These important specimens continue to be a crucial resource for studies concerning sauropod taxonomy, phylogenetic systematics, evolution and functional morphology.
