28 Days Of Dinosauria - 24

Day 24: Zuul crurivastator is an ankylosaur, found in superb condition (well - for a 75 million year old fossil, anyway) in Montana just a couple of years ago. It gets the first part of its name in honour of Ghostbusters, and the second bit, crurivastator, effectively means "destroyer of shins", as it had a whacking great club on the end of its tail. Roughly six metres long, it would have been a heavily armoured herbivore, covered in spikes and bumps, and very much not the sort of thing that you want to piss off.

There's a handy (silent) little YouTube video here that shows some of the bones, including the surprisingly cheerful skull; a life restoration; and a size comparison with an African elephant, just in case you should be needing such a thing. One minute twenty-five seconds.
