(type).

Size: Uncertain.
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.
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-M�rquez, 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.
