A new study shows that Oviraptor's compacted caudal vertebrae may actually have yielded peacock-style behavior in the animal. One theory is that this ability to raise the tail might have been used during mating rituals for shaking a small fan of feathers on the end of its tail.

Theropoda: Tyrannosauridae Where does it stand?
Well, several years ago, some teeth were discovered in China credited to a new species, Tyrannosaurus zhuchengensis. However, folks said it was nothing and ignored that claim for a new species. Now, a skull that doesn't match any known tyrannosaur has been discovered. They'd like to call it Zhuchengtyrannus magnus -- but is this just more evidence of T. zhuchengensis? If so, that's the name it keeps.
