The late Cretaceous period witnessed a perplexing array of small theropod dinosaurs, including raptors, tyrannosaurs and feathered "dino-birds." Based on the fragmentary remains of a single juvenile, unearthed in Mongolia, at least one influential paleontologist has classified Bagaraatan as a tyrannosaur, though others insist this smallish predator was more closely related to the non-tyrannosaur theropod Troodon. As with so many other obscure dinosaurs, the definitive answer awaits further fossil discoveries.
