Microcoelus

Microcoelus is a dubious genus of small titanosaurian sauropod dinosaur from the Late Cretaceous Bajo de la Carpa Formation, Argentina. It is known from only a single dorsal vertebra, although a left humerus was formerly referred to this taxon, but it is now considered to belong to Neuquensaurus. The type species is M. patagonicus, described by British paleontologist Richard Lydekker in 1893.
