In Depth

       Tanius is one of the many known Asian hadrosauroid dinosaurs,‭ ‬but one that is not very well represented.‭ ‬The initial description was based upon the back of the skull which seems to be that of a flat headed hadrosauroid dinosaur,‭ ‬the kind roughly between the earlier iguanodonts and the more advanced hadrosaurids.‭ ‬However the incomplete nature of the remains has also led to speculation that Tanius may actually be a hadrosaurid in its own right,‭ ‬possibly one of the saurolophines because of the seemingly flat head.

       At one time the lambeosaurine hadrosaurid Tsintaosaurus was considered by some to be a synonym to the genus Tanius.‭ ‬This was based upon the idea the crest of Tsintaosaurus was merely another bone that had become fossilised next to the skull to give the impression of a crest.‭ ‬However,‭ ‬when a second specimen identical to the first was found,‭ ‬the crest was definitely not a product of the fossilisation,‭ ‬and palaeontologists are today satisfied with treating the two genera as separate.‭ ‬Additionally however,‭ ‬another species of Tanius called T.‭ ‬spinorhinus is now considered a synonym of Tsintaosaurus,‭ ‬with the other species T.‭ ‬chingkankouensis and T.‭ ‬laiyangensis also being considered to be the same as Tsintaosaurus.‭ ‬Another species,‭ ‬T.‭ ‬prynadai,‭ ‬has now been moved to the genus Bactrosaurus.
