In Depth
Neuquensaurus is easily one of the smallest of the known titanosaurs, with only genera such as Magyarosaurus being known to clearly be smaller. Neuquensaurus has had a fairly complicated taxonomic history with fossils of Neuquensaurus previously being described as belonging to both Titanosaurus and Saltasaurus before being renamed as Neuquensaurus. In addition to this the genera Microcoelus and Loricosaurus may actually be synonymous with Neuquensaurus. The second species of Neuquensaurus, N. robustus is at the time of writing also considered to be dubious on the basis of a distinct lack of diagnostic features upon the fossils of this species.
