Species: B. sicinskii (type).
Known locations: Mongolia - Nemegt Formation.
Time period: Maastrichtian of the Cretaceous.
Fossil representation: Partial post cranial remains including nine dorsal (back) vertebrae, nine sacral (hip) vertebrae, 15 caudal (tail) vertebrae, left ilium (hip), partial left and right pubis, ribs and partial elements of hind limbs.
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
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
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
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.
