About Daspletosaurus:

Daspletosaurus is one of those names that sounds better in English translation than in the original Greek--"frightening lizard" is both scarier and more pronounceable! Other than its position near the top of the late Cretaceous food chain, there's not much to say about this tyrannosaur: like its close cousin, Tyrannosaurus Rex, Daspletosaurus combined a massive head, a muscular body, and many, many sharp, pointy teeth with a ravenous appetite and puny, comical-looking arms. It's likely that this genus included many similar-looking species, not all of which have been discovered and/or described.
