Khankhuuluu - The Mongolian Tyrannosaur that Clears up Tyrannosaur Evolution

I recently put out a video on the unique two-fingered therizinosaur of Mongolia, Duonychus, the description of which has helped improve our understanding of the group and how they had even more diverse morphology in their feeding methods and anatomy than was thought previously. The area of Mongolia where they’re from, the Bayanshiree formation, has now turned up yet another new dinosaur species, one of which that while also being a theropod like Duonychus, was not a therizinosaur, and was instead a Tyrannosauroid, an animal that is both important due to its help in understanding more about the groups diversity, but also about their distribution and geographical origins and range. This animal was Khankhuuluu, a basal tyrannosauroid that with its unique mixes of both derived and basal traits, has helped out our understanding of Tyrannosaur taxonomy in a wider paper that assesses how they moved in and out of Asia and North America over many millions of years, having big implications for the origins of the largest members of the group, including T.rex. I hope you enjoy!
