If you had to guess... if the Cretaceous -Paleogene extinction had never occurred, how do you think the evolution of dinosaurs would have progressed? And are there any clues or hints that you have found in the fossils of later dinosaur species which you think may be used as indicators?

There has been interest in the pigmentation of dinosaur skin. What inferences would you make about a species behaviour based upon its colouration?

I was thinking of avian species in particular, if the extinction event hadn't occured many ecological niches would have remained occupied and diversification would have been restricted. I'll always be curious to know how tyrannosaurs and raptors etc would have developed. The fact that you study behaviour is very interesting, did the revelation that some theropods were feathered have any ramifications for how dinosaur behaviour is interpreted?
