Yuanmousaurus is a genus of sauropod dinosaur that has most recently been considered to be related to genera such as Mamenchisaurus and Tienshanosaurus. This interpretation is based upon a partial cervical (neck) vertebra, at the time of writing the only part of the neck known that shows elongation similar to the neck vertebrae of mamenchisaurid sauropods.
