In Depth

       Fossils of this dinosaur were actually first mentioned in a scientific paper published in‭ ‬2008,‭ ‬but it would not be until‭ ‬2022‭ ‬that they were formally described as a distinct genus.‭ ‬Paralitherizinosaurus is a genus of therizinosaurid dinosaur that lived in South East Asia during the late Cretaceous.‭ ‬Although established upon the description of‭ ‬just a few bone fossils,‭ ‬comparison to better preserved relative genera allows us to infer that Paralitherizinosaurus was a bipedal herbivore with very long claws on its hands.‭ ‬These claws may have been aids to help Paralitherizinosaurus to feed.
