Day 09: Tarbosaurus bataar (The Asian T. rex) was slightly smaller than its North American cousin (from current fossil evidence), but just as formidable. It was another of the later dinosaurs, living around 70 million years ago, and some argue that it should be called Tyrannosaurus bataar, given the similarity between it and T. rex. At the moment, Tarbosaurus is holding its own though, as there are enough differences between them to make it appear that both species evolved to suit different environments, and probably slightly different prey. Which I'm glad about, as Tarbosaurus means "alarming lizard", which amuses me, and I should be sorry to lose the name.
