I am a dinosaur palaeontologist specialising in behaviour, ask me anything
I am a British palaeontologist specialising in carnivorous dinosaurs and the (non-dinosaurian) flying pterosaurs. I've held palaeo jobs in Germany and China and carried out research all over the world. I'm especially interested in behaviour and ecology. I do a lot of outreach online with blogs and websites.
Not proof but of interest, my other main blog: http://www.guardian.co.uk/science/lost-worlds
Last update: I think I've done all I can over the last 6 hours. We're over 1300 comments and I've produced a good few hundred of them. Thanks for the great questions, contributions and kind words. I'm sorry to those I didn't couldn't get to. I may come back tomorrow or do another one another time, but for now, goodbye.
