       Barsboldia is so far only known from vertebrae and some fragmentary remains of other‭ ‬parts of the post cranial skeleton.‭ ‬At the time of writing no skull is known for the genus,‭ ‬yet the original describers still chose to class Barsboldia as a lambeosaurine hadrosaurid dinosaur.‭ ‬Later studies however have cast doubts about Barsboldia being a lambeosaruine and one in particular‭ (‬Prieto-Márquez,‭ ‬2011‭) ‬came to the conclusion that Barsboldia was actually a saurolophine hadrosaur.‭ ‬This makes a little more sense as by the Maastrichtian period of the Cretaceous,‭ ‬lambeosaurine hadrosaurs‭ ‬had been largely replaced by saurolophine hadrosaurs.‭ ‬This would mean that Barsboldia had a small solid bone crest if at all.‭ ‬However studies of the North American genus Edmontosaurus in the early twenty-first century have now proved that some species of saurolophine hadrosaurs had soft tissue crests which only rarely got preserved.
       Coming from the Nemegt Formation,‭ ‬Barsboldia would have lived alongside other hadrosaurids such as Asian species of Saurolophus,‭ ‬as well as ankyosaurs like‭ ‬Tarchia and titanosaurs like Nemegtosaurus.‭ ‬Predatory threats to Barsboldia would have principally come‭ ‬from‭ ‬large tyrannosaurs such as Alioramus and Tarbosaurus.
