Paleo File: Bagaraatan


         Bagaraatan, which is mongolian for “little hunter”, was a small carnivorous theropod dinosaur. Polish Paleontologist, Halszka Osmólska discovered the remains of the animal in the Nemegt Formation of Mongolia 1996. Although the name might seem odd, it is the phylogenetic categorization that makes this organism an oddity.

          Halska Osmólska never pursued her findings to the phylogenetic level and left it to other scientists to decide on the fragmentary remains; A Lower Mandible, the upper legs, pelvis, and caudal vertebrae. Scientists have found three possible groups the animal may belong to; Holtz suggested a Tyrannosauroid, Coria a Troodontid, and Rauhut a Maniraptoran. However, despite the differing opinions and confounding evidence, the phylogenetic grouping so far agreed upon is Tyrannosauroidea. More fossils are needed before a concrete classification can be reached, or an appropriate reconstruction of the animal in life.
