Name: Hudiesaurus ‭(‬Butterfly lizard‭)‬.
Phonetic: Hoo-die-sore-us.
Named By: Z.‭ ‬Dong‭ ‬-‭ ‬1997.
Classification: Chordata,‭ ‬Reptilia,‭ ‬Dinosauria,‭ ‬Sauropodomorpha,‭ ‬Sauropoda,‭ ‬Mamenchisauridae.
Species: H.‭ ‬sinojapanorum‭ (‬type‭)‬.
Diet: Herbivore.
Size: Uncertain but very roughly estimated to be up to‭ ‬30‭ ‬meters long.
Known locations: China,‭ ‬Xinjiang‭ ‬-‭ ‬Kalazha Formation.
Time period: Late Jurassic.
Fossil representation: Partial remains from two individuals including a front leg,‭ ‬vertebra and teeth.

       To put it bluntly,‭ ‬the remains of Hudiesaurus are very partial,‭ ‬but they do seem to belong to a mamenchisaurid sauropod,‭ ‬or in simpler terms,‭ ‬one like Mamenchisaurus.‭ ‬The remains which are known are without doubt huge,‭ ‬and comparison to other similar sauropod genera has resulted in an estimated length of around thirty metres for Hudiesaurus.‭ ‬To some this may seem impossibly big,‭ ‬but thirty meters seems to have been the norm for Asian sauropods with some such as Daxiatitan, as well as ‭ ‬Huanghetitan and Ruyangosaurus to name some others which have all been estimated to be about thirty meters long despite the lack of more complete remains.
