Fossil representation: Remains of several individuals,‭ ‬though usually incomplete.

       Shuvosaurus was described from the discovery of a skull that had no teeth but a well-developed beak-like anterior portion.‭ ‬Because of this,‭ ‬Shuvosaurus was at the time considered to possibly be an ancient ancestor to the ornithomimosaurs,‭ ‬a group of dinosaurs that at the time of writing are only known from Cretaceous era fossil deposits.‭ ‬Later study,‭ ‬particularly the description of the genus Effigia in‭ ‬2006,‭ ‬has now yielded the conclusion that Shuvosaurus is not actually a dinosaur,‭ ‬but a form of rauisuchian.‭ ‬Because the mouth is beaked and toothless,‭ ‬it is difficult to establish what kind of diet Shuvosaurus head,‭ ‬since a beaked mouth could be used for either a carnivorous or herbivorous diet,‭ ‬possibly even both.
       Sankar Chatterjee named Shuvosaurus after his son,‭ ‬who was also the person to discover the Shuvosaurus holotype.‭ ‬The species name‭ ‘‬inexpectatus‭' ‬is a reflection of the unexpected nature of the find.‭ ‬Another genus named by Chatterjee,‭ ‬Chatterjeea,‭ ‬is now considered a synonym to Shuvosaurus,‭ ‬and hence material once labelled as Chatterjeea is now referred to as Shuvosaurus.‭ ‬Additionally,‭ ‬the vertebrae once attributed to the Gojirasaurus holotype,‭ ‬are now regarded as belonging to Shuvosaurus.
