problem with Bagaraatan is that it is only known
from partial remains
that in themselves could be placed within a variety of different
theropod groups. Leading palaeontologists have described Bagaraatan
and even a maniraptorian, all of the main
carnivorous theropod classes that were active in Asia towards the end
of the Cretaceous.
Named after the Mongolian for 'small hunter', the only thing that can be said about Bagaraatan is that it was a bipedal dinosaur, like other theropods, and that it was a carnivore.
