In Depth

       Neimongosaurus is a genus of therizinosaur that lived in Asia during the late Cretaceous.‭ ‬Like other therizinosaurs,‭ ‬Neimongosaurus was descended from meat eating theropods,‭ ‬though the teeth in the lower jaw of Neimongosaurus which have coarse serrations‭ ‬which‭ ‬indicate that Neimongosaurus were plant eaters.‭ ‬Neimongosaurus has occasionally been classed as a member of the Therizinosauridae,‭ ‬though the original idea as well as later interpretations of Neimongosaurus is that it actually belongs in the Therizinosauroidea,‭ ‬meaning that it was more primitive in form.
