1996 outline showing known elements
Bagaraatan (meaning "small hunter" in Mongolian) was a genus of theropod dinosaur from the Late Cretaceous period. Its fossils were found in the Nemegt Formation of Mongolia. Bagaraatan may have been around 3–4 metres in length.
The type species, B. ostromi, was described by Osmolska in 1996. The post-cranial (ZPAL MgD-I/108) skeleton has been described as "bird-like", while the skull exhibits features of several different theropod groups.
Classification
Holtz classified Bagaraatan as a basal tyrannosauroid, Coria identified it as a troodontid, and Rauhut placed it in Maniraptora. Mark Loewen et al. placed it in basal tyrannosauroidea, agreeing with the placement by Holtz.[1]
